Summary

This report documents a linear static analysis of the assembly untima_struttura_asm which was imported from the file F:/STUDIO/ANSYS/aaa/untima_struttura_asm.igs and subjected to the load environment Environment 1 . The analysis was performed using the ANSYS 8.0 CAE software. The assembly untima_struttura_asm was assigned properties of the materials given in Table 2 and showed the following results:

Maximum total displacement is 0.21011 mm Maximum equivalent stress is 29.041 MPa

For details about the analysis, see Model Information, Analysis Information, and Results Information.
