New publication
We are pleased to share that our paper “Thermomechanically Coupled Visco-Hyperelastic-Plastic Model with Self-Heating for Thermoplastics” has just been published in Computer Methods in Applied Mechanics and Engineering.
In this work, we develop a thermodynamically consistent finite-strain constitutive framework for semi-crystalline thermoplastics. The model combines visco-hyperelasticity, plasticity, temperature-dependent material behavior, and mechanically induced self-heating. By accounting for the influence of temperature and crystallinity on the material parameters, the formulation enables a more realistic description of the rate- and temperature-dependent response of thermoplastic materials under large deformation.
The constitutive update is implemented using automatic differentiation and GPU-vectorized computations, supporting robust and efficient integration in finite element simulations. This work contributes to the predictive simulation of thermoplastic components under thermomechanically coupled loading conditions relevant to manufacturing and engineering applications.
