An effective boundary element algorithm for 2D and 3D elastoplastic problems
X. Gao, T. G. Davies. International Journal of Solids and Structures 37 (2000) 4987-5008,-0001,():
Novel methods are described for removing the strong singularities arising in the domain integrals of elastoplasticity, and for solving the non-linear equation set. The former employs a new transformation from domain integrals to (cell) boundary integrals. The number of system equations is minimised by using the plastic multiplier as the primary unknown and an incremental variable stiffness iterative algorithm is developed for solving these equations. Excellent convergence is achieved and some numerical examples demonstrate the algorithm's effectiveness.
