Bathe Assigned: 02/07/2008 Due: 02/14/2008 Problem 1 (10 points): Consider the sheet of material shown. Here ? ? ± = ° ? ± ² + ± ² ? ? ² = ° ? ² + ± Also, the stresses are ³ ? ±± = ? ³ ? ²² = ²? ´µ¶ ³ ? ±² = ? Identify three simple independent virtual displacement patterns and show that the principle of virtual work is satisfied for these patterns. 2" 2" x 1 x 2 t f x2 = 20 psi (tension) configuration at time t configuration at time 0

Unformatted text preview: the elements to 4-node elements and compare the results. Note: To change the elements, just delete the previous mesh and remake the mesh using 4-node elements by setting “ Nodes per element ” to 4 (default value is 9 as used in the example). Compare the calculated stresses with the two meshes along the two symmetry lines and discuss your results with a few sentences.
