3.1.3.4.1. Interface
The Interface element models cohesive or contact interfaces between continuum
parts. It is used to simulate delamination, peeling, and traction-separation
behaviors using appropriate interface constitutive laws.
3.1.3.4.1.1. Overview
Element type: Interface
Supports:
- Traction–separation laws via material models (e.g., XuNeedleman)
- 2D and 3D interface formulations depending on mesh and setup
- Nonlinear analysis for softening and debonding
