1. Introduction
Summarize the FEM analysis on truss_structure_final
Note:
Do not base your design
decisions solely on the data presented in this report. Use this information in
conjunction with experimental data and practical experience. Field testing is
mandatory to validate your final design. COSMOSWorks
helps you reduce your time-to-market by reducing but not eliminating field
tests.
