Upper figure: (a) Schematic illustration of the experimental configuration. Homalite samples are cut with an inclination angle and compressed with the far field load. Dynamic photoelasticity and laser velocimeters are used to capture the full field information of rupture propagation as well as local sliding velocity of the interface. Rupture nucleation is conducted by the means of exploding wire technique. Lower figure: (b) Photograph of the actual setup. Details of the laser velocimeters and Homalite samples are revealed.
