NEi Software Presents New Nastran Modal Analysis Tools at Symposium

By DE Editors

NEi Software (Westminster, CA) will present a technical paper on “Modal Selection Technique for Component Mode Synthesis,” an enhanced methodology for performing dynamic analysis of very large FEA models measured in multi million degrees of freedom,  at the Shock and Vibration Information Analysis Center’s (SAVIAC) 79th Shock and Vibration Symposium October 26-30 in Orlando, FL.

In addition, NEi Software will conduct several tutorials on new features in its simulation software. The NEi Nastran Nonlinear course will address proper techniques for analyzing models with nonlinear geometry,  materials, and elements. The NEi Composites tutorial will demonstrate Progressive Ply Failure Analysis (PPFA), an NEi Software tool that examines the residual strength after first ply failure in a laminate structure which allows engineers to mitigate catastrophic failure modes in parts optimized for strength-to-weight criteria. A session on the Dynamic Design Analysis Method (DDAM) will explain the steps in determining the dynamic response of a structure to shock loading.

The Shock and Vibration Information Analysis Center (SAVIAC) is a jointly funded activity sponsored by the Army, Navy, Air Force, DTRA, and the DOE laboratories and operated by HI-TEST Laboratories, Inc. in Richmond, VA.
