Single Edge Crack

Application ID: 988

This model deals with the stability of a plate with an edge crack that is subjected to a tensile load. To analyze the stability of exciting cracks, fracture mechanics can be utilized.

A commonly used parameter in fracture mechanics, used to predict if a specific crack will cause the plate to fracture, is the so-called stress intensity factor KI. When this calculated value becomes equal to the critical fracture toughness of the material, KIc, (a material property) then fast, usually catastrophic fracture occurs. In this model, you determine the stress intensity factor KI using the so-called J-integral.

The combination of COMSOL® products required to model your application depends on the physics interfaces that define it. Particular physics interfaces may be common to several products (see the Specification Chart for more details). To determine the right combination of products for your project, you should evaluate all of your needs in light of each product's capabilities, consultation with the COMSOL Sales and Support teams, and the use of an evaluation license.
