Case Study: Predicting Virtual Allowables

During the process of designing lightweight CFRP structures, one usually needs access to allowable values. However, allowables generation is particularly costly and time-consuming. Each characterized material system must cover various layups, coupon tests, and environment conditions. Each test configuration must be repeated many times to obtain a statistical evaluation of the mechanical property. With advanced …

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 …

Structural Analysis of a Tilt-Blade Rotor Mechanism

Question: Given an assembly, such as the rotor mechanism shown below, how can one determine the stresses and potential failure modes? Answer: Nonlinear FEA available in MSC Nastran can be used for structural analysis to assess the behavior of contacting rotor mechanisms. This presentation Contact Model of Rotor Components provides additional details on how to model …

Getting Students Ahead of the Curve

Engineering Simulation has become a critical, if not fundamental, part of the design and development process at all forward looking companies, big and small. Students entering the job market are expected to be familiar with simulation technologies and have proficiency in Computer Aided Engineering (CAE) solutions, which would also give them an edge in the …

Over Designing Fiber Reinforced Plastics

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 …
