2D Spall Fracture in long rod Simulation Package for ABAQUS — Petrov-Morozov VUMAT for PMMA

This package provides a complete workflow for simulating spallation (dynamic tensile fracture) in 2D axisymmetric geometry using ABAQUS/Explicit. It is aimed at researchers and engineers working with PMMA and similar brittle polymers under shock loading. What’s included: VUMAT subroutine with Petrov-Morozov failure criterion — rate-dependent damage based on stress history over a characteristic time window Spall_2d_auto.py — parametric Python […]
