Title:Analysis and optimization of weakly coupled thermo-elastic-plastic systems with applications to weldment design
Author(s):Michaleris, Panagiotis; Tortorelli, Daniel A.; Vidal, Creto A.
Subject(s):Weakly Coupled Thermo-elasto-plastic Systems
Weldment Design
Abstract:A systematic approach for the design of weakly coupled thermo-elasto-plastic systems is presented. The solution process uses the Newton-Raphson iteration method so that analytic design sensitivity formulations may be efficiently evaluated via the direct differentiation technique. The derived formulations are suitable for finite element implementations. Analysis and sensitivity analysis capabilities are combined with numerical optimization to form an optimum design algorithm. To demonstrate the algorithm, a weldment is optimally designed with respect to manufacture and service life aspects.
