FEA Modeling from Start to Finish Part 1: Preprocessing and - PowerPoint PPT Presentation

FEA Modeling from Start to Finish Part 1: Preprocessing and Analysis IN THIS WEBINAR: PRESENTED BY: • Geometry import and editing David Cross, Ph.D. • Meshing and Applying loads Senior Aerospace Stress Engineer • Running a static analysis Structural Design and Analysis david@structures.aero 5/22/2012 Page 1

Agenda 1. Analyze support brackets mounted to exterior of a pressure vessel. 2. Begin with a breakout orthogrid panel section and utilize enforced displacements to simulate the internal pressure. 3. Mid-surface the bracket geometry and mesh the bracket mid-surfaces. 4. Model the various connections between the brackets and the orthogrid panel. 5. Define the boundary conditions, enforced displacements, and loads, and use data surface to create load set combinations. 6. Create the linear static analysis set. 5/22/2012 STRUCTURES .AERO Page 2
