Static and dynamic fracture mechanics analysis of a DCB specimen considering shear deformation effects

Static and dynamic fracture is analyzed in a DCB specimen considering shear deformation effects. The DCB specimen is assumed to consist of two Timoshenko beams bonded together along a common edge except at the crack surfaces and is subjected to two splitting forces. Because of symmetry, only one half of the model is considered. So, the physical model of the problem consists of a Timoshenko beam lying on an elastic Winkler foundation. The problem...
