Assembly Modeling of Aerospace Structures Using Contact Simulation

Bolted or riveted airframe assemblies are typically modeled as continuous meshes. But advances in meshing and solver technology are changing the way we model these assembly structures. Today, continuous meshes are often replaced by individually meshed parts joined together by some type of connector or interaction definition. These individually meshed parts are typically joined together …

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 …
