Project 4 – Finite element modeling and analysis (contact analysis): Due: Thursday 6/23/05 Grade weight: 10% of your total project grade A block (10in x 10 in x 5 in) is at rest on a horizontal plane. Use the default steel material in I-DEAS for the block and the plate. The bottom of the plate is restrained from moving in all DOF. The coefficient of static friction between the block and the plate is 0.5. An evenly distributed force is applied to one of the vertical surface. Mesh both objects with a mapped mesh. Determine the maximum force that can be applied without causing the block to overcome the static frictional force. Solve the model for two load cases: the first with a force slightly less than the maximum allowed force, and the second load case with a

Unformatted text preview: force that is slightly higher. Study the displacements for both load cases and explain the displacements. Did you obtain any warnings? If so, explain what you think they mean. Determine the reaction forces and verify them with a Free-Body-Diagram and equilibrium equations. Do this for both load cases? Explain your results. The report should include the above and : Short description of the mesh. A print out of the mesh summary (# of nodes etc.) Short description of the boundary conditions. Short description of the loads. A detailed description on how the contact was modeled. Pictures and discussion of the deformations A picture of the stresses in the x-, y-, and z-directions. A reaction force file...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
