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 […]

High-velocity impact simulation of Rubber-Toughened Poly Methyl Methacrylate (RT-PMMA) reinforced with CFRP

RT-PMMA/CFRP High-Velocity Impact Simulation Rubber-toughened poly(methyl methacrylate) (RT-PMMA) reinforced with carbon-fiber-reinforced polymer (CFRP) is an advanced hybrid material system designed to combine the optical clarity, lightweight characteristics, and strain-rate sensitivity of PMMA with the high specific strength and stiffness of carbon-fiber composites. Such hybrids have growing relevance in engineering applications that demand excellent impact resistance—such […]
