Chapter 70: Adaptive Crack-Initiation and -Propagation

This example problem shows how to simulate crack-initiation and fatigue crack-propagation in structural components. The analysis uses Mechanical APDL SMART technology. The structure is a CT specimen with holes.

The following features and capabilities are highlighted:

  • SMART-based crack initiation and propagation

  • Defining material and crack geometry for a crack-initiation domain in 3-D structures

  • Solution controls for adaptive crack initiation

  • Mesh controls for crack-growth analysis

For more information, see SMART Method for Crack-Initiation Simulation and SMART Method for Crack-Growth Simulation in the Fracture Analysis Guide.
