摘要： A method (10) for performing stress-based topology optimization of a structure (2, 102, 202) on a computational device (302) is provided. Upon receiving a problem definition of the structure (2, 102, 202) from an input device (304) coupled to an input of the computational device (302), the method (10) may generate a density filter, interpolation schemes for stiffness, volume and stress, a global stress measure, an adaptive normalization scheme and a regional stress measure, to determine an optimized stress-based solution to the problem defined. The method (10) may further enable the optimized solution to be rendered for display at an output device (306) coupled to an output of the computational device (302).

摘要： A system for determining a welding sequence is disclosed. The system may have a welding sequence generator configured to create an initial population of welding sequences based on a user-generated constraint. The system may also have a welding simulator configured to simulate welding for at least one welding sequence in the initial population of welding sequences to model distortion for the at least one welding sequence. The welding sequence generator may be further configured to receive the distortion for the at least one welding sequence in the initial population from the welding simulator, determine whether a merit value derived from at least the distortion for the at least one welding sequence satisfies one or more predetermined criteria, output the at least one welding sequence as a potential welding sequence if the merit value satisfies the predetermined criteria.
