Structure Preserving Space Time Discretization In A Mixed Framework For Multi Field Problems In Large Strain Elasticity

Structure-preserving space-time discretization in a mixed framework for multi-field problems in large strain elasticity

Thermodynamically consistent space-time discretization of non-isothermal mechanical systems in the framework of GENERIC

The present work addresses the design of structure-preserving numerical methods that emanate from the general equation for non-equilibrium reversible-irreversible coupling (GENERIC) formalism. Novel energy-momentum (EM) consistent time-stepping schemes in the realm of molecular dynamics are proposed. Moreover, the GENERIC-based structure-preserving numerical methods are extended to the context of large-strain thermoelasticity and thermo-viscoelasticity.

Multi-field modeling and simulation of fiber-reinforced polymers

This work proposes a new numerical approach for analyzing the behavior of fiber-reinforced materials, which have gained popularity in various applications. The approach combines theories and methods to model the fracture behavior of the polymeric matrix and the embedded fibers separately, and includes a modified plasticity model that considers the temperature-dependent growth of voids. Tests are conducted to explore different types and sequences of failure in long fiber-reinforced polymers.
