Disclaimer . 1 ABAQUS Tutorial – 3D Stress Analysis Consider the problem studied previously using plane stress analysis. While nothing is gained by using a 3D finite element analysis for this problem, it does provide a simple demonstration case. For this demonstration, we will not impose symmetry as we did for the plane stress analysis. Again, this is not ideal modeling practice. The problem to be considered is a 4” x 2” x 0.1” aluminum plate (E=10e6 psi, ν =0.3) with a 1” diameter circular hole subjected to an axial stress of 100 psi. Determine the maximum axial stress associated with the stress concentration at the edge of the circular hole. Compare this solution with the design chart (ref. Mechanical Engineering Design, 5 th edition, Shigley and Mischke, 1989) value σ max = 2.18 (200 psi) = 436 psi. The geometry can be created using Abaqus drawing tools or by importing a part created in a CAD package. For this tutorial, we will demonstrate both creating the part in Abaqus and importing a part created in Solidworks. In Solidworks, saving the part in either ACIS (.sat) or Parasolid (.x_t) format works well. 2-D Problem
