In a PVC plate, there is an elliptical through-the thickness cavity. The dimensions of the cavity are: major axis=2 mm, minor axis =0.5 mm. If the stress far away from the cavity is 300 MPa, what is the maximum stress generated in the plate?
To determine the maximum stress generated in the plate due to the presence of an elliptical through-the-thickness cavity, we can use the stress concentration factor. The stress concentration factor is a dimensionless factor that accounts for the increase in stress around a cavity or notch in a material.For an elliptical cavity, the stress concentration factor can be approximated using the following equation:
