The dynamics of the crack front in a <em>fluid-driven <\/em>fracture are particularly interesting due to the strong coupling between the fluid and the elastic medium. We visualize circular fluid-driven fracture using high-speed imaging and find that the crack propagation is unstable: long pauses of no motion are followed by rapid forward jumps.

These results highlight the importance of transverse dynamics in the forward propagation of extended fractures.<\/p>\n\n\n\n<div class=\"wp-block-group has-white-color has-primary-background-color has-text-color has-background has-link-color wp-elements-fc8393f09267808759caf7601247ce3d has-dark-background\"><div class=\"wp-block-group__inner-container is-layout-flow wp-block-group-is-layout-flow\">\n<h5 class=\"wp-block-heading\">Read more<\/h5>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"has-md-font-size\">T.\u00a0Cochard, I.

These rupture fronts separate the sticking and sliding regions; macroscopic motion is initiated only after such a front has traversed the entire frictional interface. Describing the coupling between the propagating ruptures, frictional interface, and macroscopic sliding is key to understanding friction. Our work experimentally established the mapping of frictional rupture fronts to cracks: The classical fracture mechanics framework describes the singular elastic fields in the rupture tip vicinity, the equation of motion of these ruptures, their arrest, and stress-wave radiation. This fracture-based description of friction replaces the idea of a characteristic static friction coefficient.<\/p>\n\n\n\n\n\n<div class=\"wp-block-group has-white-color has-primary-background-color has-text-color has-background has-link-color wp-elements-7cfe2155a7d4f6d73767701a853bfc20 has-dark-background\"><div class=\"wp-block-group__inner-container is-layout-flow wp-block-group-is-layout-flow\">\n<h5 class=\"wp-block-heading\">Read more<\/h5>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"has-md-font-size\">I.
