Researchers capture how material break apart following an extreme shock

To see how materials respond to intense stress, researchers shocked a copper sample with picosecond laser pulses and used X-ray laser pulses to track the copper’s deformation. They captured how the material’s atomic lattice first compressed and subsequently expanded,, creating pores, or voids, that grew, coalesced, and eventually fractured the material.

An international research team has used ultrabright X-rays from SLAC's Linac Coherent Light Source, to observe how materials deform and fail when impacted by a powerful shock. A better understanding of the failure process will help researchers design new materials that can better withstand intense events such as high-velocity impacts. This experiment focused on understanding ultrafast material deformation. The researchers plan future experiments under conditions that more closely match real-world applications.
