This paper presents an elastoplastic soil model considering the principal stress rotation (PSR). The model is developed on the basis of a well-established kinematic hardening soil model using the bounding surface concept. The significance of including the PSR in soil models is presented through comparing the predictions using the new and original models. The model can consider the PSRs under multiple directions, and features relatively simple formulations and easy numerical implementations. Model predictions are compared with different experimental results and verified. Simulations of multiple dimensional PSRs are also studied.
