Fracture Mechanics in Workbench v14.5 - e-Learning Presentation

This presentation accompanied the Fracture Mechanics in Workbench v14.5 ANSYS e-Learning session, originally given in July 2013 by CAE Associates. To view a recording of the session, click here.

The presence of a crack in an engineering structure does not necessarily result in the immediate failure of the structure. In fact, most engineering components contain cracks. Assessing the remaining life of a cracked structure is the goal of linear elastic fracture mechanics. Fracture mechanics can be used to determine if an existing crack will propagate due to a static loading, and it can be combined with fatigue life prediction to determine crack propagation under cyclic loading.

This e-Learning session demonstrates some approaches to assessing life of structures with cracks using fracture mechanics within the ANSYS Workbench environment.

Topics Covered:

  • Review of linear elastic fracture mechanics.
  • Description of finite element methods for calculating near-crack stress behavior.
  • Review of approaches for crack propagation fatigue analysis.
