Subjective Laser Speckle Method And Its Application To Solid Mechanics Problems

Abstract

The basic principles of the subjective laser speckle method are reviewed with an analysis of its sensitivity and limitation. Emphasis is on the method's application to various solid mechanics problems. Examples cited include stress concentration due to discontinuities, determination of thermal stresses, flexure of plates, vibration of composites, fracture of aluminum, interior strain determination, impact stresses, nondestructive testing of debond in lavprpri nnmnncitpc atom
