摘要: Abstract The paper addresses the numerical simulation of strain localisation in stiff clays that exhibit softening behaviour. An elastoplastic constitutive model developed to incorporate key features clay behaviour is described first. A non-local formulation then introduced for regularisation analysis localisation. series analyses were conducted explore relevant aspects 3D was also performed assess suitability approach presented applications. Finally, application a laboratory test on Beaucaire marl results an excellent reproduction experimental observations.
