Stress Analysis of Photo-Elastic Orthotropic Composite Material and Measurement Fringe Value of Shear Material

Abstract:

Based on the analysis characteristics of orthotropic composite material under antisymmetric force, a new measurement method is established which can independently measure the fringe value of optical shear orthotropic material by pure-shear experiment. Two orthotropic photo-elastic composite material beams with rectangular cross-section which fiber orientation is 0 °, 90 ° respectively are loaded anti-symmetric force, so that the anti-symmetric section is in a pure shear stress state. The fringe value of orthotropic photo-elastic shear composite material is measured . The results agree with three stripe specimens tensile experiment.
