Lightweight, High Performance Composites – Progressive Ply Failure Analysis (PFA)

Question: What is progressive ply failure analysis (PFA)? Answer: PFA is a type of analysis used to model the failure of a composite laminate on a layer by layer basis. From Andrew Main's Use of Finite Element Analysis to Create Robust Composite Designs – Going Beyond First Ply Failure. This analysis approach allows the structure to ...

Lightweight, High Performance Composites – How to Account for the Uncertainty in Composite Material Properties

Question: How can I account for the uncertainty in composite material properties? Answer: You can perform a Stochastic Analysis. I've quoted a description from Andrew Main's Use of Finite Element Analysis to Create Robust Composite Designs – Going Beyond First Ply Failure. Stochastic analysis is not a method that was developed for composites but the large ...

Lightweight, High Performance Composites – Using FEA to Predict the Gradual Failure of Adhesives

Question: How can FEA be used to model the gradual failure of adhesives in composites? Answer: You use the cohesive zone modeling technique. Here is quick explanation of CZM from Andrew Main’s Use of Finite Element Analysis to Create Robust Composite Designs – Going Beyond First Ply Failure. Unlike virtual crack closure, cohesive zone modeling ...
