Abstract
In the article the method of dynamic photoelasticity is used to investigate the formation of a state of stress at the apexes of cracks and notches under the action of stress waves. Edge and closed cracks in the case of the action of longitudinal and surface waves are discussed. The investigations show that a crack may be simulated by a notch only under definite conditions.
