Airplane noise is an important factor for airlines to consider due to several industry changes in recent years. Increased competition, more air traffic, and construction of communities near airports has created several new issues for aerospace engineers to take into consideration, including quality perception from customers and new regulations from both local and federal governments. Turbofan …
Acoustic Simulation For the Aeronautical Industry With the expansion of air travel around the world, competition between airlines has become much tougher. Airplane companies are under constant pressure from governments around the world to reduce noise and from consumers to reduce the cost of air travel. For many companies, noise is a chronic …
Launching a rocket into the sky is not an easy thing. There are several thousands of unimaginably complex engineering processes occurring in the background, the competition is getting tougher every day, and companies frequently only have one chance to get the launch sequence right. So what is hindering efforts to launch more powerful rockets in …
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 …
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 …
Attend our seminar in Southern California on April 23, 3013 Attend training in Indiana on May 30, 2013 Imagine you have designed a part, only to find out later the predicted maximum stresses are in fact lower. It’s too late to make any design modifications, and now your part is produced for a maximum stress …
