Plastic UMAT for Abaqus

If you need linear elastic or Mises plastic UMAT and related CAE models please visit this link: https://www.engssoft.com/elastic-plas... This video is the last part of a series, which help you step by step, to write your own first plastic UMAT subroutine. The UMAT is based on Mises plasticity and linear isotropic hardening. In the first video of this series, basics of Mises plasticity were explained. In the next video, the algorithm which is used to solve Mises equations is depicted, then Jacobian matrix was described in a separate video. In this video, plastic UMAT subroutine is described based on the described equations in previous videos. If you are interested to start writing your own plastic UMAT this series is really helpful. In this video you can find out: Introduction 00:00 UMAT interface descriptions (important variables) 00:39 Variable definition 03:54 Elastic stiffness matrix 04:23 Elastic stiffness matrix 04:23 Trial stress 05:24 Newton iteration 06:44 Stress Update 08:13 Jacobian matrix 08:46
