A new brittle-elastoviscoplastic fluid based on the Drucker–Prager plasticity

A new brittle-elastoviscoplastic (BEVP) fluid model is presented in this paper. This relatively simple to use, as it contains few material parameters and a fixed-point algorithm effective for solving the coupled system of equations. The combines some existing fundamental features such elasticity, plasticity brittle damage. combination them based on thermodynamics that ensures positivity dissipation Onsager symmetry. Moreover, allows point out link between thixotropy damage context elastoviscoplastic (EVP) fluids. Theoretical results Drucker–Prager criterion are completed order use here. Preliminary with proposed BEVP very encouraging: able represent pre-failure, failure post-failure behavior quasi-brittle materials.
