Videos of experimental ruptures
Full-field quantification of dynamic ruptures
The full-field behavior of dynamic ruptures is quantified by using ultrahigh-speed photography in combination with digital image correlation and highly tailored analysis (learn about the method here). The movies below are obtained for a supershear rupture propagating at 2.3 km/s.

Capturing the evolution of dynamic friction
The evolution of friction is visualized by tracking in real time friction changes with slip and slip rate for spontaneously propagating dynamic ruptures. The movie below shows the friction measurements obtained for two experimental ruptures, based on our newly developed ultrahigh-speed technique to capture dynamic ruptures. The approach to quantify dynamic friction and the interpretation of the measurements is given here.

Visualization of pressure and shear shock fronts in viscoelastic materials
The movie below shows the formation of pressure and shear shock fronts for a rupture propagating in a viscoelastic material (PMMA) at a speed of 2.6 km/s.
