Task : 1 You are expected to analyses the structure using analytical and FEA method that you consider to be appropriate for obtaining a particular level of accuracy. Perform a static stress analysis with linear material models on the problem shown in Figure 1 utilizing different mesh densities. Use meshes of 200, 400, 800, and 1600 elements. The thickness of the part given below is 8mm. A load of 10 MPa is applied on the right edge. The left end is fully fixed. Material is stainless steel (AISI 302) cold rolled. Assume it as a plane stress problem. Calculate stress concentration factor and compare with that of given in mechanics textbook. Write your comments in comparison with analytical solution  stress analysis Task : 2 Analyse a beam model using different element types and compare the results. A n kPa load is acting downward along the top, where n is the last three digits of your UWE ID number. (for instance, for student 14020174, n is 174). The left end is fixed, and the right end is simply supported. Material steel (AISI 4130). Length of the beam is 250 mm along y-axis. The cross-section is rectangular (13mm along z-axis & 6mm along x-axis) Use following elements in ANSYS and fill the table below. a) 1-D beam element: Convert the n kPa surface load over the width to a 3,600N/m distributed load. b) 1st Plate element: Model 250mm x 13mm dimension and enter a thickness of 6mm. The pressure must be converted to forces on top edge as follows:
  • Width * Pressure = Force
  •  Force/2 located at the ends.
c) 2nd Plate element: Model 250mm x 6mm dimension and enter a thickness of 13mm. The pressure is applied as a n kPa surface load. d) Brick: The pressure is applied as a n kPa surface load.
