What is Lode Dependences in Elastoplastic Models about?
The document discusses formulations to account for the Lode angle in isotropic pressure-sensitive elastoplastic materials. It reviews seven existing Lode dependences from the literature and proposes a new one called LMN to generalize previous failure surfaces. As an illustration, several Lode dependences are introduced into the Roscoe and Burland plasticity model. The performance of the modified model is estimated by comparing experimental and analytical results for true triaxial loadings on normally consol
