Popis: | The design sensitivity of a thermo-elastic-plastic system is considered. The continuum approach and resulting finite element formulations are described. Sensitivity is obtained by an incremental load approach for nonlinear response analysis. Kinematic and isotropic hardening in thermo-elasto-plasticity are discussed. The control volume approach is to analyze shape and nonshape design. The direct differentiation method is adopted to obtain the design sensitivity expression for the response variables. Analytical examples demonstrate the developed sensitivity procedure. The design sensitivity formulas are discretized to implement it as a computer program with isoparametric finite elements. Numerical examples are presented to calculate the design sensitivity. |
