From: A laboratory study of hydraulic fracturing at the brittle-ductile transition
Images of the post-mortem samples tested following procedure P2 (see Methods) at \(20\,^{\circ }\)C and \(60\,^{\circ }\)C. The complex fracture pattern observed with procedure P1 disappears, and overall a classical pure mode-I planar hydro-fracture develops independently of temperature.
