Breaking the Mesh Dependency: A New Standard for Blast and Fragmentation Simulation
Modeling natural fragmentation under explosive loading is difficult due to extreme deformation, mesh dependency, and loss of mass in traditional finite element approaches. This case study explains how Impetus overcomes these issues using robust higher-order elements, a mass-conserving node splitting algorithm, and stochastic damage modeling to stabilize crack initiation. It also highlights the Erode to SPH (E2S) capability for handling severe target interactions within a unified workflow.
Mastering the Foerster/Munroe Effect: A New Paradigm in Shaped Charge Simulation
Shaped charge design requires modeling liner collapse, jet formation, and high-velocity target interaction鈥攑rocesses that often exceed the limits of conventional Lagrangian methods. This case study presents Impetus鈥� coupled FE/SPH approach, validated against research benchmarks, and highlights its Shaped Charge Template for streamlined setup. It also explains the Erode to SPH (E2S) capability for preserving mass and momentum during penetration events.
De-Risking Survivability: A Strategic Approach to Ballistic Protection with Impetus VAA
Meeting STANAG 4569 protection levels requires identifying structural weak areas such as seams, welds and plate boundaries鈥攖raditionally through destructive testing. This case study shows how the Impetus VAA tool uses ray-tracing and critical thickness calculations to evaluate millions of potential hit locations efficiently. A real-world application with Iveco Defence Vehicles demonstrates how digital vulnerability mapping supported certification and predicted 94% of observed perforations.
