Rigid Impact with Peridynamics

High-fidelity simulation of dynamic impact and damage—fully in the cloud.

SolidNetics' Rigid Impact with Peridynamics module brings advanced impact and high-rate dynamic behavior modeling to engineers through an intuitive cloud-based workflow. Peridynamics naturally captures large deformations, damage, separation, and material failure—making it ideal for simulating impact events where traditional FEM struggles due to mesh distortion or complex crack patterns.

This module uses an explicit peridynamic solver for transient dynamics, enabling accurate prediction of deformation, stress waves, and damage evolution under high-speed collision. Engineers can study impact resistance, material failure, penetration response, and multi-impact scenarios directly in the browser.

Rigid Impact with Peridynamics

Overview

Peridynamics (PD) replaces spatial derivatives with integral equations, enabling robust simulation of highly nonlinear and discontinuous behavior—without remeshing or special impact/contact algorithms.

In dynamic impact problems, PD excels at:

  • High-strain-rate deformation
  • Stress-wave propagation
  • Damage initiation and evolution
  • Fracture under impact loading
  • Interaction between rigid bodies and deformable solids

This makes PD a powerful tool for simulating ballistic events, drop tests, penetration, crushing, and any high-speed interaction between rigid and flexible components.

SolidNetics delivers all of this through a fully cloud-based system—no local installation, no HPC setup, and no coding required.

Why Peridynamics? Why SolidNetics?

Superior modeling of high-speed events

Peridynamics naturally handles:

  • Large deformation
  • Material separation
  • Damage accumulation
  • Fragmentation under impact
  • Wave propagation into damaged regions

No remeshing. No element distortion. No penalty-based contact.
