Dynamic Stress Intensity Factor of Homalite-100

Abstract

Dynamic stress intensity factors of Homalite-100 determined by T. Kobayashi and Dally are compared with those previously obtained by the authors where similarities in the two results for single-edged notch specimens of various configurations are noted. Dynamic stress intensity factors of Araldite B obtained by Kalthoff, Beinert and Winkler and those of Homalite-100 obtained by the authors are then compared and again similarities in the two results and in particular the scatters in experimental data for wedge-loaded DCB specimens of different sizes are noted. All three teams of investigators used static near- field solution to compute the dynamic stress intensity factors from recorded dynamic isochromatics or dynamic caustics. Errors generated through this use of static near-field solutions as well as through the use of larger isochromatic lobes are thus discussed. (Author)
