Peridynamics.jl

Peridynamics v0.4.0

Diff since v0.3.3

Breaking changes and new features

• Material parameter overhaul
  Failure behavior is now controlled by passing or omitting Gc / epsilon_c.

  • No need to explicitly disable failure for elastic simulations.
  • no_failure! replaces failure_permit!.

• Enhanced correspondence model (CMaterial)
  Renamed from NOSBMaterial. Now with:

  • Kernel support: linear_kernel, cubic_b_spline_kernel
  • Constitutive models: LinearElastic, NeoHooke, MooneyRivlin, etc.
  • Stabilization: ZEMSilling (default)

• Stress and von Mises export
  Add :stress or :von_mises_stress to the fields in Job(...) for enhanced VTK output.

• Bond-associated model (BACMaterial)
  Based on Chen & Spencer (2019), supports a custom bond_horizon.

Other improvements

• Use any two elastic parameters (E, nu, lambda, mu, G, K) — the rest are auto-calculated.
• BBMaterial now accepts nu = 0.25.
• Kernel functions are now available for OSBMaterial as well.
• New benchmark/ folder for performance testing.
• New data boundary conditions with velocity_databc! and forcedensity_databc! (experimental).
• Started adding docstrings for key internal functions.
• Various bug fixes and documentation improvements.
