Question: How can FEA be used to predict the crack propagation of adhesives and resins in composites? Answer: You use the virtual crack closure technique. These methods work well for brittle adhesives, but if you have more flexible adhesives, use the cohesive zone modeling technique. Here is quick explanation of VCCT from Andrew Main’s Use of ...
