Abstract
In this paper, transparent dynamic photoelastic experimental hybrid method for propagating cracks in orthotropic material was developed.Using transparent dynamic photoelastic experimental hybrid method, we can obtain stress intensity factor and separate the stress components from only isochromatic fringe patterns without using isoclinics. When crack is propagated with constant velocity,the contours of strsess components in the vicinity of crack tip in orthotropic material are similar to those of isotropic material or orthotropic material with stationary crack under the static load. Dynamic stress intensity factors are decreased as crack growths . It was certified that the dynamic photoelastic experimental hybrid method was very useful for the analysis of the dynamec fracture mechanics.
