Dynamic stress intensity factors in viscoelastic solids were measured during various macroscopic average strain rates at fracture by a caustic method. It is found that the dynamic stress intensity factors only depend upon the running crack velocity, irrespective of strain rates applied. Much higher local strain rate may be supposed to exist at the very running crack front even at quasi-static tension loading condition.
