Motivation Peridynamics (PD)

  • alternative to classcical continuum mechanics
  • PD integral equation
  • focus material modeling and crack propagation no continuity for the displacement
transparent

PD Solving the integral - Material point method

Advantages

  • fast to implement
  • cracks are easy to include
  • discretization

Diadvantages

  • convergence is lower
  • surfaces are not known

PeriHub - Empowering Research with Peridynamic Modeling

  • Web Framework for Peridynamic Analysis
  • Open Source
  • Features
    • Generate 2D or 3D peridynamic meshes
    • Run simulation locally or on clusters
    • Analyse results directly in the browser

Generate model

RVE

Composite

Crack Analysis Tool (CrackPy)
