<p>PURPOSE:To predict stress and displacement after molding with a metal die and to design the metal die on a computer without repeating an experiment and a test concerning the stress distribution analysis system for analyzing the stress distribution of a shape to be molded by the metal die. CONSTITUTION:This system is provided with a rigidity matrix generation part 7 for generating a rigidity matrix K to be decided by a Young's modulus and a Poisson modulus specific to a designated material for each divided element, load vector generation part 8 for generating a load vector P to be impressed to the surface of an object on designated border conditions, and stress vector calculation part 9 for calculating a stress vector sigma to be stocked at each element corresponding to a displacement vector (u) of each element calculated from these generated load vector P and rigidity matrix K, and the calculated displacement vector (u) and stress vector sigma for each element are outputted.</p> |
