COMPOSITE MATERIAL DESIGN DEVICE, COMPOSITE MATERIAL DESIGN METHOD, AND COMPOSITE MATERIAL DESIGN PROGRAM USING GENETIC ALGORITHM

摘要

A purpose of the present invention is to provide a composite material design device, a composite material design method, and a composite material design program that use a genetic algorithm which can automatically design an appropriate lamination order. The composite material design device (1) using a genetic algorithm comprises: a first generation generating unit (11) that generates, as a first-generation group of individuals, a plurality of individual models using each of laminate member models having strength directionalities designed on the basis of a load condition; an evaluating unit (12) that segments each individual model in the generated group of individuals into predetermined cells, and evaluates a lamination pattern in each cell using at least one of indices including symmetry, adjacent directionality, and continuous laminability; and a next generation generating unit (14) that selects an individual model from the group of individuals through ranked selection, generates a new individual model through crossover, replication, and mutation, and updates the group of individuals as a next generation.
