Abstract: A method for determining a welding sequence including a plurality of welding operations is disclosed. The method includes steps of determining a population of welding sequences based on a set of user-generated constraints, and simulating welding for at least one welding sequence in the population of welding sequences to obtain a multi-objective dependent distortion model of the at least one welding sequence. The method further includes steps of comparing a merit value of the multi-objective dependent distortion model for the at least one welding sequence with one or more predetermined criteria, and outputting a set of welding sequences as potential welding sequences based on the comparison between the merit value and the multi-objective dependent distortion model.

Abstract: A method for performing fatigue-based topology optimization of a structure on a computational device is provided. The method may include receiving first data pertaining to a problem definition of the structure; generating a density filter; generating interpolation schemes for stiffness, volume and fatigue; generating a global fatigue measure; generating an adaptive normalization scheme; generating a regional fatigue measure; generating second data based on the first data, the density filter, the interpolation schemes, the global fatigue measure, the adaptive normalization scheme and the regional fatigue measure, the second data pertaining to an optimized solution to the problem definition; and displaying the optimized solution at an output device.

Abstract: 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).
