NEI Software will participate in the Shock and Vibration Information Analysis Center's (SAVIAC) 79th Shock and Vibration Symposium from 26-30 October in Orlando, Florida.
NEI Software will present a technical paper on 'Modal Selection Technique for Component Mode Synthesis', a methodology for performing dynamic analysis of very large FEA models measured in multi-million degrees of freedom.
In addition, NEI will conduct several tutorials on new features in its simulation software.
The NEI Nastran Nonlinear course will address techniques for analysing models with nonlinear geometry, materials and elements.
Software technology will be demonstrated that enhances nonlinear analysis in Nastran.
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 optimised 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.
Utilising NEI Nastran's DDAM, users can determine the effects of underwater explosions from sources such as depth charges, mines, missiles and torpedoes.
SAVIAC's annual Shock and Vibration Symposium is a forum for the structural dynamics and vibration community to present and discuss new developments and on-going research.
Topics covered at the symposium include: shock testing, weapons effects, air blast, ground shock, water shock, cratering, penetration, shock physics, earthquake engineering, structural dynamics, shock and vibration instrumentation and experiment techniques.
Over 200 technical papers are typically presented.
Panel discussions address topics such as new software developments and accelerometer isolation problems.
