Consider design of an axially loaded notched rectangular plate with an offset hole as shown in Figure 1. The plate has dimensions: lengths L = 200 mm, L= 190 mm, width w, thickness t, notch radius r, and hole diameter d located at (x,y). An axial tensile force, F = 25 kN is acting on the left and right edges as shown. For the case of a notched plate with a centrally located hole, where the hole center is located at (x,y) = (L/2, w/2), the maximum axial stress can be estimated from the charts shown in Appendix A-15. LL te -L. Figure 1. Plate Geometry 3 LL Perform a finite element analysis using SolidWorks to determine the magnitude and location of the maximum von Mises stress. Use the material properties given in Table 1 and the parameters given in Table 2. Assume plane stress conditions. Perform several analyses with coarse, medium, and fine meshes, especially in the vicinity of the stress concentrations. Through trial and error, convince yourself that further mesh refinement will not significantly change the results. Prepare a report that includes: 1. Your results recorded on the attached Solution Summary sheet 2. The maximum axial stresses for case of a notched plate and a plate with a center hole of diameter, d, and plate width, w. Note that for the uniaxial state of stress, the axial stress equals the von Mises effective stress. 3. The maximum von Mises effective stress associated with a notch and offset hole as obtained from the finite element results. 4. Attach a screen shot of your undeformed finite element model with coarse, medium, and fine mesh.
