Abstract
We use lattice simulations to study the dynamics of cracks under appli ed strains in brittle materials in the presence of substantial viscous dissipation. This is probably a physically relevant limit in real bri ttle materials. In large samples, cracks accelerate in the absence of viscous effects and become unstable against branching. With viscosity, cracks have a limiting velocity and long straight cracks can be stabl e.
