You may work with others, but your submission must be unique, and you must be able to completely explain everything you turn in. Simply copying a solution, or part of a solution, is not acceptable and is a breach of academic integrity. Similarly, any MATLAB code you submit should be distinct; your entire study group should not submit identical code. 1) For the solid shown below. Assume E = 2 x 10^8, v= 0.3. Determine the following. a) Divide the entire solid into at least 12 triangular elements. Show a sketch of the mesh including node and element numbers. b) Calculate the nodal forces from the surface traction (500 Pa) applied to the solid. To calculate the nodal force, multiply the traction by the surface area of the element (length x thickness) and apply half of the force to each of the two nodes on the surface. c) Solve the problem and show displacements and stress maps. Repeat the steps a), b) and c) but using the symmetry of the problem. In other words, only model half of the problem. To obtain the same results, you need to constrain the horizontal displacement in the nodes at the symmetry plane and apply half of the 300 N load. Show displacements and stress maps and make sure you get the same values as those when the whole model was solved. e) Include your Matlab code. 1m- //////////// -1 m- Thickness t= 0.2 m -1m-1m- 300 N point load 500 Pa traction 1 m 2m
