heal.abstract	The method of caustics has been applied to investigate crack propagation and interaction between a main propagating edge-crack and a collinear stationary one in plane specimens subjected to impact loading applied in a three-point bending mode. The high sensitivity of the experimental method used, combined with variable collinear crack configurations, has disclosed interesting results, concerning the continuosly variable dynamic stress and strain distributions around the propagating main crack. This arrangement of sensitive cracks was able to verify the existence and relative motion of the neutral zone appearing ahead of the moving crack tip, which separates regions of tensile and compressive transient stress in bent bars. © 1984.	en
