Abstract:This paper describes the formulation of a three�dimensional elastoplastic analysis for a pile�soil system and its application to an actual in�situ test. In the formulation, the subloading surface model is adopted for the elastoplastic constitutive relation. This model falls within the framework of unconventional plasticity, in which the plastic strain rate due to the stress rate inside the yield surface is taken into consideration.Thus it is capable of describing smooth transition from elastic to plastic state… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
