White paper explains determination of critical flaw size in a gun-launched 40mm grenade


Abaqus Explicit finite element analysis code

Simulia has published a white paper explaining the determination of critical flaw size in a gun-launched 40mm grenade.

First, Abaqus Explicit finite-element analysis code is used to conduct interior ballistic simulation of a 40mm shape charge projectile.

Second, the explicit model results are passed to Nasgro software for critical flaw-size determination using the linear-elastic fracture-mechanics theory.

The modelling information and approach to the problem will be presented in this paper, as well as explicit model results and proposed inspection criteria.
