METHOD OF DESIGNING MULTICOMPONENT MATERIAL, OPTIMIZATION ANALYZER AND STORAGE MEDIUM ON WHICH MULTICOMPONENT MATERIAL OPTIMIZATION ANALYSIS PROGRAM IS RECORDED

摘要

A material composed of many components is easily designed. Known composition ratios etc. and mechanical behaviours of the components are inputted to a nonlinear arithmetic unit (32) through an experimental data input unit (40) in an optimizer (30). The nonlinear arithmetic unit (32), which is a conversion system of a neural network, learns the relations between the compositions etc. of the component materials of the multicomponent material and their mechanical behaviours. The ranges, etc. which restrict the mechanical behaviours such as Young's moduli, etc. and the composition ratios of the component materials which are to be optimized are inputted through an optimization item input unit (42). An optimization arithmetic unit (34) estimates the mechanical behaviour of the multicomponent material in accordance with its composition ratios etc. by using the optimization items and the conversion system of the arithmetic unit (32) and optimizes until an object function which is the mechanical behaviour is converged. The optimized composition ratios etc. are outputted from an optimization result output unit (44).
