THE CASE FOR EXPLICIT FINITE ELEMENT ANALYSIS OF FABRIC SYSTEMS, A PRESENTATION OF REAL WORLD APPLICATIONS AND RESULTS
This paper presents the application of Finite Element Analysis (FEA) to real world problems typically encountered in the Aerodynamic Decelerator Systems field, and to fabric engineering in general. All simulation results are presented from the commercially available Explicit FEA package LS-DYNA, as this has been our most successful application. Our experience with the application of Implicit FEA, is that commercially available codes cannot handle the large deflections associated with fabric systems. The presentation of test to simulation comparisons, now available from several projects, is also presented herein. These provide the reader with a feel for the level of precision/validation possible with today’s simulation tools. Finally, we close with a discussion of where Irvin, and eventually our industry, will apply computational techniques in the coming years.
