Abstract:

Isochromatic patterns associated with dynamic brittle crack propagation were recorded by means of a modified Schardin multiple-spark-gap, dynamic polariscope for 10 x 10 inch edge crack panels. With the material properties determined by dynamic calibration, the resulting photoelastic information was used to evaluate the elastic fields surrounding the propagating crack by the semi-inverse technique. This solution was characterized by the dynamic stress intensity factor whose behavior was determined for accelerating, constant velocity, and arresting cracks. Author
