Problem 1 (20): The plate shown in figure below is analyzed for static stress. One end of the plate is fixed and a normal tension force of 1001bf is applied on the other end as shown in figure 1. For a medium mesh size (.75") the maximum stress is shown in figure I the von Mises stress results are shown in figure 2. A) Does the part fail under distortion energy theory failure criteria? What is the Factor of Safety based on distortion energy theory failure criteria? B) Does the factor of safety under Maximum Shear Stress theory increase or decrease or remain the same? Why? C) If the material below is a brittle material what conclusions can you make for the failure of the material and FOS? D) Since we chose the mesh size to be 0.75", can we draw a conclusion that the stress value is independent from the mesh size? Why? E) Should the plate be checked for failure under buckling? Why?
