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 ...

Lightweight, High Performance Composites – Predicting crack propagation of adhesives and resins

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 ...

Simulating the Manufacturing Process

Improve your FEA of composites Question: How do you accurately simulate manufacturing processes? Answer: You use Marc, the advanced nonlinear simulation solution. When Setforge Engineering set upon simulating the electro-upsetting process used to make very long sectional parts,  Nicolas Behr, Chief Project Engineer, had this to say about Marc: We now know that we can ...

Nonlinear Analysis – Optimization of a Traditional Wrench

Topic: A colleague of mine recently forwarded me a paper titled Virtual DOE of an Open-End Wrench. What caught my attention was the use of design of experiment to create a new wrench called the Claw. Does it actually look like a claw? Yes. For those interested in reading more about the use of Design ...
