Question

Relocate the hole and fillet by placing them closer or further away from their current position and discuss the change in stress concentrations for different positions. Plot the stress concentrations at different locations as function of distance between the hole and fillet. Is there any optimum location for lower stress concentrations for both features?

0.125 in. 1.25 in. 1875 in. r 0.25 in. 0.75 in. Solve the problem of a long steel plate with a hole and fillet as given in figure using COMSOL. The given plate with a hole and fillet is subjected to tensile load of P- 2 kips. The total length of the plate is 6 inches, the center of the hole is 2inches away from the left end and the fillet is 2 inches form the right end. You can choose any material you like. Report should have the following:

Answer 1

The three cases were explored for the given geometry. In all the three cases, the position of hole was different.

The geometry was modeled in COMSOL Multiphysics and the given load was applied. The material properties were given the properties of steel.

二二二二

In the third case, when the hole was near to the fillets, the total area of stress concentration was more. So, it can be concluded that the breakage is more likely in third case.
