The Stress Field Surrounding a Rapidly Propagating Curving Crack

Source

Results are presented from experiments conducted with a cross-shaped, biaxial fracture specimen which was eccentrically loaded to obtain rapid crack propagation along a curved path. High-speed photographs of the crack-tip isochromatic patterns were analyzed to obtain the leading coefficients of the dynamic, mixed-mode, crack-tip stress field expressed in series form. Values of K_II associated with the propagating crack were found to be essentially zero when compared with the dominant opening mode stress intensity factor, K_I.
