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 […]
Impact analysis of the CFRP/PEEK/ceramic/gelatin composite for finding behind the armor trauma
Impact analysis of the CFRP/PEEK/Ceramic composite for finding behind the armor trauma In this tutorial, the impact analysis of a CFRP/PEEK/ceramic/gelatin composite panel for evaluating behind-armor trauma (BAT) has been carried out in Abaqus. The carbon fiber reinforced polymer (CFRP) is modeled as a three-dimensional shell part with elastic layers and Hashin’s damage criterion to […]
Impact Analysis and Simulation Package
Introduction to Impact Analysis This course offers an in-depth study of impact dynamics and numerical simulation using Abaqus. It is designed to provide students, researchers, and practicing engineers with both theoretical understanding and practical skills in modeling a wide range of impact scenarios. Through systematically structured examples, participants will learn to model and analyze high-velocity […]
