designing using ANSYS and calculation
Budget: $10 – $40 USD
1. Develop a 3D model of the cantilever beam and the supporting plate using Solidworks software or ANSYS modeling utility and then conduct your failure analysis using ANSYS finite element modeling (FEM) package. – 10 points
2. Determine the maximum deflection and stress values using ANSYS for the applied force of F = 4500 N and the fillet radius of r=6 mm. Calculate the factor of safety of the design for the given force magnitude and then estimate the maximum allowable force that can be applied to the structure. Compare your ANSYS results with the ones obtained from the analytical solution. Assume that the back face of the supporting plate is fixed as the boundary condition. Change the mesh size and repeat the same analysis and show the results on a compact graph. – 40 points
3. Determine the effect of changing fillet radius on the results of static analysis. Construct a graph of geometric stress concentration factor versus fillet (r/d) and then compare it with the graph given in the textbook. Assume that the back face of the supporting plate is fixed as a boundary condition. – 20 points
4. Perform dynamic failure analysis of the beam under fully reversed loading with a force magnitude of 5000N. Calculate the factor of safety of design where the load is applied in cycles of 15 seconds duration for 2 years (each of 300 days) and 4 hours per day (r=6mm). Assume that the back face of the supporting plate is fixed as the boundary condition. Construct the S-N curve for the data given below. Compare your ANSYS results with the results obtained from the analytical solution. – 20 points
5. Perform a modal analysis and find the mode shapes and frequencies. Assume that the back face of the supporting plate is fixed as a boundary condition. – 10 points
