RISExperimental Investigation of 3-D Crack-Tip Deformation Using Moiré-Sagnac Interferometry
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A combined moiré-Sagnac interferometry method was applied for in-plane and out-of- plane crack-tip surface deformation measurement. Based on 2-D and 3-D Jacobian derivative method (JDM), a stress ...
