•Objective•Cad model•Manufacturing sheet.•Fea model•Basic analysis methods implemented.•Loading condition with respect to the analysis methods.•Material and property•The results•conclusion

objectiveTo do some thing “”FTP””

To verify the analytical skills with the help of CAD/CAE tool and also with the microsoft tool.

To verify the tool knowledge to achieve the goal.

The CAD model

Manufacturing model• 2.5mm sheet with aluminum alloy • 2.5mm sheet with aluminum alloy

Outer face with offseted FEA model

Direct Transient analysis (0-1.6 with

cosine function)1. Direct transient analysis:-

I. Magnitude and the location are same as static analysis with a function of cosine with phase 250 and time range is 0.0 to 1.6.

II. Boundary condition is same as static analysis.

Load and boundary condition in direct transient response analysis

Load and boundary condition for static x-directional loading

Load and boundary condition for static y-directional loading

Load and boundary condition for static Z-directional loading

Load and boundary condition for direct transient x,y,z-directional

loading Full constrained area

Load as per static with time function
