Title:
METHODS AND SYSTEMS FOR MODELING MATERIAL BEHAVIOR
Document Type and Number:
WIPO Patent Application WO2003087746
Kind Code:
A3
Abstract:
A method for modeling material behavior includes using empirical three-dimensional non-uniform stress and strain data to train a self-organizing computational model such as a neural network (Fig. 15). A laboratory device for measuring non-uniform stress and strain data from material includes an enclosure with an inclusion in it (Fig. 1, item 12). As the enclosure is compressed, the inclusion induces a non-uniform state of stress and strain. A field-testing device includes a body having a moveable section (Fig. 4, item 18). When the body is inserted in a material and the moveable section moved, a non-uniform state of stress and strain can be characterized.
