A Displacement Pattern Matching Application in Elastic-Plastic Hybrid Stress Analysis
Abstract
A two-dimensional hybrid experimental-numerical technique for elastic-plastic stress analysis is presented. This technique results from merging two relatively new technologies in engineering mechanics: boundary element methods and image processing. A syntactic pattern recognition scheme termed Displacement Pattern Matching determines displacement boundary conditions to be used in an elastic-plastic boundary element (EPBEM) code. The result is an automated stress analysis tool. Displacement pattern matching is a process where displacements are measured by tracking an arbitrary array of black spots on a white specimen are compared in a double exposure format to determine displacements. Displacement pattern matching is a full-field technique, with spatial resolution on the order .0001 inch.
