【期刊论文】A study of constitutive relation and dynamic failure for SFRC in compression

This paper presents a study of constitutive relation and fracture failure of steel-fiber reinforced concrete (SFRC) subjected to compressive loading. Firstly, the characteristics of stress–strain curves for SFRC are analyzed, and appropriate constitutive relations are suggested. Subsequently, an erosion algorithm is presented for the simulation of the fracture failure of the SFRC. With the erosion criterion of maximum principal strain implemented, the failure of the SFRC specimen in split Hopkinson pressure bar (SHPB) tests is finally simulated. Numerical results show that the isotropic hardening plasticity mode and the erosion criterion are suitable for the analysis of the SFRC failure under medium strain-rate loading. In addition, the volume fraction of fibers has significant influence on SFRC fracture failure.

The protection of underground structures against dynamic loadings has long been a topic of great interest in defense engineering. This paper focuses on the far field blast wave propagation and attenuation in rock shelter layer with an inclusion or filled medium. First, the effect of single inclusion on wave attenuation is explored analytically assuming that the interfaces between rock and the inclusion are completely consolidated. The formulae for the strength of total transmitted stress and velocity wave after the inclusion are subsequently presented. At last, numerical studies on the attenuation of one dimensional P wave in rock embedded with artificial cavity, steel plate and natural joint are carried out. The attenuation rules for various scenarios are discussed in detail in this paper which can provide useful guidelines to the design of intelligent defense structures.

Based on experimental results, this paper firstly evaluates the effect of fibre aspect ratio (length-to-diameter) on mechanical characteristics of steel fibre reinforced concrete (SFRC). Analysis reveals that the aspect ratio has an optimal value for strengths in every concrete batch. Beyond this value, the addition of steel fibres into concrete may have an effect of increasing the ductility rather than the strengths. Subsequently, crater and perforation in two SFRC targets by a steel projectile are numerically simulated based on erosion algorithm. The effective stress and effective plastic strain are tabulated to model the softening behavior due to post-yield damage. Numerical results show that the hydrodynamic model is able to describe the responses of SFRC under impact loading. Besides, higher aspect ratio of fibres can absorb more energy, causing smaller craters in SFRC target and lower residual velocity of the projectile.

【期刊论文】Modelling of blast-induced fractures in jointed rock masses

This paper focuses on the dynamic fracturing process of jointed rock masses due to blast wave loading. A coupled numerical method using both LS-DYNA (a transient dynamic finite element program) and UDEC (an universal discrete element code) is outlined first. The blast-induced fracture extension in two representative jointed rock masses is studied subsequently. Besides, the effects of loading density of explosive charge on fracture evolution and the effects of the preexisting earth stress and free face on the fracturing process of rock masses are also explored in detail. The numerical results capture some of the well-known phenomena observed in the field and expected theoretically, and thus can offer useful guidelines to blasting design in rock masses.

This paper focuses on the propagation and dynamic effects of blast waves in faulted rock masses. A coupled method combining UDEC and LS DYNA is presented whereby the explosion process is simulated by LS DYNA while the wave propagation and its dynamic effects in rock masses with faults are modeled by UDEC. Tile blast induced crack evolution and failure zone distribution in faulted rock masses are explored using the proposed coupled method. Tile relationship between rock failure and fault parameters such as dip, stiffness and friction are also investigated. Tile results indicate that the coupled method is feasible and effective for evaluating explosion in discontinuous rock system and the existence of faults exerts significant influence on the pattern of rock masses failure.

【期刊论文】A method for evaluating dynamic tensile damage of rock

This paper presents two evolution laws for dynamic tensile damage of brittle rock based on light gas gun (LGG) tests. By analyzing the attenuation of sound-wave propagation in the rock samples before and after impact tests, one evolution law for dynamic tensile damage of rock is introduced and incorporated into the finite element code LS-DYNA through a user-defined subroutine. The improved code is then applied to the simulation of the tensile damage and blast crater near free face of rock mass, and the resulting crater geometry is compared with empirical formula. In addition, based on the phenomenological point of view and the velocity–time histories recorded in LGG tests, another evolution law of tensile damage is proposed to consider the nucleation and growth of microflaws in rock. Parametric analyses are carried out with the self-developed finite difference code and an optimization procedure for the parameter determination is suggested.

【期刊论文】Numerical analysis of blast-induced wave propagation and spalling damage in a rock plate

The paper focuses on the numerical analysis of blast-induced stress wave propagation and related spalling damage in a rock plate or wall. Firstly, a large-scale contact explosion is simplified as a one-dimensional (1-D) strain problem, and a cross-format centered finitedifference scheme is presented. Secondly, the finite-difference code is used to explore the wave propagation in a rock plate, and compared with the commercial software LS-DYNA. Thirdly, a continuum damage constitutive model for rock is introduced and successfully incorporated into the LS-DYNA through its user-defined subroutine. Coupling with the erosion technique, the improved LS-DYNA is used to simulate the blast-induced spalling damage at the back-side of rock plate. Numerical results show that the 1-D finite difference code is convenient and accurate. Also, the user-defined subroutine can well describe the process of spalling damage.

The prediction of blast crater in brittle rock due to an underground explosion has gained importance in recent years due to the great number of accidental events that affected engineering safety. This paper uses the Taylor-Chen-Kuszmaul (TCK) continuum damage model to analyze dynamic fracture behavior of rock in tension due to blast loading. The TCK damage model, together with an erosion algorithm, was implemented into the explicit FE code, LS-DYNA, as a constitutive augmentation. The damage pattern around the blasthole and the formation of blast crater near a free surface were subsequently simulated using the developed numerical tool. It is shown that the free surface is vitally responsible for the blast crater. Furthermore, the size and shape of the blast craters can be reasonably predicted if the erosion criterion of critical tensile damage is well calibrated. The effects of common charge modes on blast craters were also investigated numerically, and the mechanisms of the coupled, air-decoupled and water-decoupled charge mode are compared and presented.

Civil defense shelters are often constructed beneath the ground to provide protection against blast loadings. Concrete is widely used as the material for the defense layer of the shelters. This paper adopts a continuum damage model of brittle media to numerically investigate the dynamic fracture and attenuation effect of perforated concrete defense layer on stress waves from planar charge. The model includes damage accumulation and loading rate-dependence, and has been succinctly implemented into the dynamic finite element code, LS-DYNA, via its user defined subroutine. The numerical results reveal that the adopted model can well predict the tensile damage owing to the reflection of pressure waves from cavities and free boundaries. Again, the elastoplastic properties of concrete play significant roles in the stress-wave attenuation and the peak values of hydrostatic pressure beneath a circular cavity are largely reduced. One empirical formula is finally proposed to relate the decay factor of peak hydrostatic pressure to the cavity dimensions and relative position.

【期刊论文】Numerical study on craters and penetration of concrete slab by ogive-nose steel projectile

In the design of defense structures, concrete slabs are often used to provide protection against incidental dynamic loadings such as the impact of a steel projectile. In the present study, the Taylor-Chen-Kuszmaul (TCK) continuum damage model is further improved and successfully implemented into the dynamic finite element code, LS-DYNA, with erosion algorithm. The numerical predictions of impact and exit craters of concrete slab as well as the residual velocity of projectile using the newly-implemented numerical tool show good agreement with experimental observations. The performance of the modified TCK model is evaluated by comparing with the material Type 78 (Mat_Soil_Concrete) and Type 111 (Mat_Johnson_Holmquist_Concrete) available in LS-DYNA. The effect of CRH (caliberradius-head) ratio of the ogive-nose projectile on the impact crater is also investigated using the new numerical tool. Finally, the maximum penetration depth of steel projectile into a concrete slab is studied and an empirical formula is proposed.
