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