Improved Explicit Numerical Integration of a Highly Nonlinear Elasto-Plastic Constitutive Model

When implementing a highly nonlinear stress-strain model to solve boundary-valued problems, one of the major challenges is how to reduce the accumulative error and to maintain the effectiveness of the numerical integration. In general, the conventional explicit algorithm tends to have a lower computational efficiency and a higher accumulative error. In order to deal with these challenges, this paper proposes an improved-explicit algorithm …
