Please answer question #13 only! ( don’t answer other questions) Please type your answer, don’t solve on solid works ( type only answer for question #13 only) Using the part "Cross pipe" given in the attachment. 1) (5 points) Change the Default configuration to " Sharp Edge" 2) (10 points) Add another configuration named "2 Round Edge 3) (5 points) With the configuration "2 Round Edge" active, create a fillet of 0.1" at the inner edges 4) (15 points) Using the configuration "1 Sharp Edge", create Static study named "Sharp mesh 1" with the top and bottom ends fixed, the right side face is applied a 1000N down force, the mesh size is by default. Run the study 5) (10 points) Duplicate the study "Sharp mesh 1" and name it "Sharp mesh 2". Use "Apply Mesh Control" with the upper inner edge closest to the load. The mesh size is 0.1 inch. Run the study 6) (10 points) Duplicate the study "Sharp mesh 2" and name it "Sharp mesh 3". Edit definition of "Mesh Control-1" with the mesh size of 0.07 inch. Run the study 7) (5 points) Duplicate the study "Sharp mesh 3" and name it "Sharp mesh 4". Edit definition of "Mesh Control "with the mesh size of 0.04 inch. Run the study 8) (5 points) Duplicate the study "Sharp mesh 4" and name it "Sharp mesh 5". Edit definition of "Mesh Control- 1" with the mesh size of 0.01 inch. Run the study 9) (10 points) Using the configuration "2 Round Edge", create a Static study name "Round mesh 1" with same setting of study "Sharp mesh 1" in part 4). Run the study 10) (5 points) Duplicate the study "Round mesh" and name it "Round mesh 2". Recreate mesh with "Curvature based mesh" with default values Run the study 11) (S points) Duplicate the study "Round mesh 2" and name it "Round mesh 3". In "Curvature based mesh", increase the "Minimum number of elements in a circle" to 12. Run the study 12) (15 points) Create the table similar to Figure 3-10 including all studies created.

As given in the above problem , vonMises's stress is created due to the failure of distortion energy theory when itis maximum.
Energy required for shape deformation of the material is called distortion energy.
1 Sharp edge is diverging due to sharp edge modeled in solid works.
This value is a scalar stress which can be determined by using cauchys stress tensor.
Mathematically the vonMises's yield criterion can be expresses as J2 = k2
where 'k' is the yield stress.
We know that von Mises Stress is widely used by designers to check if their design will work for the required load condition for safety purpose before investing in the raw materials.
The designers design will fail if the von Mises stress will be greater than the strength of the material.
Von mises stress is created only when the distortion energy in simple tension case is less than the distortion energy in actual case.
In the given figure at the sharp edge the value of von Mises stress should be less than the yield stress value of the material to be safe (i.e withstand the load condition)
