Haftka, “Optimal Structural Design with Plate Finite Elements”, ASCE, J. Structural Div., Vol. 105, No. ST11, Nov. 1979. Analysis Type(s): Optimization (/OPT) Static Analysis (ANTYPE = 0) Element Type(s): 2-D Structural Solid Elements (PLANE42) Input Listing: vm155.dat Test Case Minimize the weight (volume) of a cantilever beam subject to an end moment, M. The stress σmax may not exceed 30,000 psi anywhere nor may the deflection δymax be greater than 0.5 in. The thickness of the beam may vary along the length, with the thickness at the poi...
