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 […]

Deformation behavior of single and multi-layered materials under impact loading

Papers abstract: Finite element (FE) simulations using Abaqus/Explicit are performed to study the deformation behavior of materials under impact loading. Various configurations including monolithic and multi-layered plate having combinations of ceramic, metal and composite material layers are investigated to determine the critical failure velocity Vcf as a function of layer thickness and stacking. While cylindrical […]
