Memory repositioning in soil plasticity models used in contact problems

Abstract We aim to enhance the stability of finite element models dynamic structural contact with multiphase granular soils which are described by advanced soil plasticity that can simulate monotonic and cyclic behaviour soils. Often, numerical oscillations cannot be avoided in these cause significantly overshoot stress, leading unrealistic discontinuities stress paths. This situation challenge integration scheme global solver lead early termination analysis. specifically address issue overshooting presenting novel solutions corresponding schemes for a representative model unsaturated Also, several examples provided evaluate show advantages limitations proposed solving contact-impact problem involving
