CVEN 445H Matrix Methods of Structural Analysis Fall, 2001 Due: October 22, 2001 (Monday, 8:0000000 a.m.) COMPUTER HOMEWORK ASSIGNMENT 9 Solve Problem 7.10 on page 335 of Prof. Logan’s textbook. Use Abaqus and approximately 100 to 150 nodes. (That is you do not need to solve the problem using 25, 50, 75, and 120 nodes as stated in the textbook). Exploit symmetry. Use triangular elements. Note: you should consider using the Abaqus command “Averaged at nodes” for obtaining stress values at the nodes of the elements. Without this specification, nodal stresses are reported at the Gauss integration points. Also, if you use Patran (see below) you need not redo the problem with Abaqus and a ‘hand-generated’ mesh. Required: For submission, interpret!!! the output. Put boxes around important quantities such as deflections that you use on your sketches. Use Abaqus Viewer (or, better, Patran – see below for Bonus City) to draw the undeformed and the deformed shape of the structure for each of the two simulation cases. Mark up the diagram with important quantities. Cut down drastically on the size of the .dat file that you print out (i.e. save a few trees). Include a table that summarizes your answers for each of the two cases of Young’s modulus and. Poisson’s ratio (see statement of problem in your book). In this table, show a small sketch to indicate the location (and direction) on the member of the maximum principal stresses. BONUS CITY Use Patran to help you solve Problem 7.10. Heavy hint: See the TAMU Abaqus/Patran User’s Manual, page 67, for a step by step description of “platehole.db” which is very similar to your problem.
