  • Molded-component stress-strain curve estimation device
    Patent number: 7937183
    Abstract: A molded-component characteristic estimation device that estimates the stress-strain curve of each portion of a molded-component includes a storage unit that stores correlation data showing the correlation between solidification time and mechanical characteristics of a material for the molded-component; and a controller that estimates solidification time of each portion of the molded-component using a shape model of the molded-component, calculates a mechanical characteristic value of each portion based on the correlation data and the estimated solidification time, and estimates the stress-strain curve of each portion of the molded-component based on the calculated mechanical characteristic value. With this device, the stress-strain curve of each portion of the molded-component is estimated without actual measurement.
