Optical and Finite-Element Investigation of a Plastically Deformed Surface Flaw Under Tension

Source

A combined moiré method has been used to experimentally obtain three-dimensional surface deformations in a plastically deformed tensile strip containing a surface flaw. A finite-element approach using experimentally obtained displacements as boundary conditions is followed to investigate the interior deformation fields and to study several parameters of interests such as J, crack-tip singularity and J, crack-mouth opening displacement equivalence for a chosen specimen geometry.
