Amplitude modulation of a low-coherence source, applications to distance and dynamic displacement sensing

The utility of the hybrid experimental-numerical method in elastic and elastoplastic fracture mechanics is demonstrated through a fracture process zone analysis and a J-integral computation, respectively. For the former, the crack bridging stresses in the fracture process zones of concrete and alumina fracture specimens were determined through an inverse analysis and the dissipated energies in these zones were quantified. For the latter. J-integral was shown to be highly path dependent with stable crack growth.
