Integration of Rigid-Plastic Simulation Engines into Engineering Database System for Advanced Forging
In the advanced forging, nondestructive forgeability evaluation as well as productive modeling are indispensable to predict the limit of working especially for new materials, to describe the change of geometries and dimensions in process and to make preform designs. For those purposes, engineering database system is preferable to process thus obtained data by both rigid-plastic simulations and experiments and to provide thus evaluated informations through retrievals and functional operations. Architecture of our developing engineering database system is presented and discussed with the rigid-plastic simulation engines. Through crack sensitivity evaluation, the limit of upsetting is estimated with comparison to experimental results.
