Sample Stress Analysis Report
1. Foreword
Purposes of the
strength analysis for 16 ton Carriage & Girder have adequate strength to
support to lift 32ton load,
This analysis is
carried out using ANSYS Workbench 15 Static Structural program,
Material used for
analysis is ASTM 36 with min Yield Strength 235 N/mm2
