Thermo-Elasto-Viscoplastic Modeling of Polymers in Abaqus | UMAT Subroutine
€ 340.0
Package Description
The training package centers on Finite Element Analysis (FEA) using Abaqus Standard, specifically focusing on the implementation of advanced constitutive models via Fortran subroutines. The core engineering methodology is a coupled thermo-mechanical finite strain formulation utilizing a multiplicative decomposition of the deformation gradient. The provided code reveals a sophisticated UMAT (User Material) subroutine that implements a “Two-Part” material model structure: Part A features rate-dependent plasticity governed by an Eyring flow rule, while Part B utilizes a hyperelastic network model characterized by a “Locking stretch” parameter, typical for large-deformation polymer mechanics.
This comprehensive training course includes detailed PDF and video tutorials that rigorously cover the underlying theory and mathematical formulations of finite strain kinematics, including Polar decomposition and Hencky strain calculations. The curriculum features a dedicated line-by-line investigation of the UMAT code, guiding users through complex algorithms such as the substepping scheme for numerical integration and the consistent tangent stiffness tensor calculation. Practical application is enforced through specific workshops, most notably the “Tension” simulation derived from the inp file, where users will simulate and analyze tensile deformation under coupled thermal conditions. By the end of this course, users will gain the practical skills necessary to develop, debug, and deploy custom thermo-viscoplastic material subroutines for high-fidelity engineering simulations.
