The objective of this research program is to investigate experimentally the transient strain and stress distribution in the vicinity of a running crack in engineering materials. The elasto-dynamic state of stresses in the neighborhood of a rapidly running crack tip was determined experimentally for developing relations between the dynamic stress intensity factors under opening mode and mixed-mode loadings. Originator supplied keywords include Dynamic photoelasticity dynamic moire crack curving Crack branching.
