Abstract

Dynamic crack response to Mode II shear wave loading was studied by ultrasonic fractography. The maximum crack deflection angle Ξ′ and the modulation depth h were evaluated using a surface roughness-measuring instrument. The result showed that Ξ′ depends on the amplitude of the applied shear waves and decreases with the crack velocity V_f. The modulation depth h changes as a function of product Ξ′ V_f and increases linearly with the crack velocity when Ξ′ is constant.
