A prominent rupture mode is self-healing slip pulses, which feature a finite slipping zone. The physics of slip pulses is qualitatively different from their expanding crack-like counterparts, as they involve the interplay between leading-edge contact breakage and trailing-edge re-strengthening (healing). The latter is intrinsically related to generic properties of frictional interactions at contacting interfaces, absent in ordinary fracture of bulk materials. In this talk, I will review a recently developed theory of two-dimensional slip pulses, which revealed intriguing dynamical properties of slip pulses and provided extensive predictions for their spatiotemporal evolution. The theoretical predictions are supported by large-scale numerical simulations and, more recently, by extensive laboratory experiments. The implications and potential applications of the theory will be discussed as time permits. <br>\r\n<br>\r\n<strong>References</strong>:\r\n<ol>\r\n\t<li><a href=\"https://www.pnas.org/doi/10.1073/pnas.2309374120\" target=\"_blank\" title=\"open  in new window\">The dynamics of unsteady frictional slip pulses</a> [PNAS 120, e2309374120 (2023)]</li>\r\n\t<li><a href=\"https://www.sciencedirect.com/science/article/pii/S0012821X26000142\" target=\"_blank\" title=\"open in a new window\">An equation of motion for unsteady frictional slip pulses</a> [EPSL 678, 119831 (2026)]</li>\r\n\t<li><a href=\"https://arxiv.org/abs/2608.26065\" target=\"_blank\" title=\"open in a new window\">Lab earthquakes confirm the theory of frictional slip pulses</a> [arXiv:2608.26065 (2026)]</li>\r\n</ol>\r\n<br>\r\n<strong>Biography:</strong><br>\r\nEran Bouchbinder is a Professor at Weizmann Institute of Science, Israel.
