What is Gradient elasticity with surface energy: Mode-I crack problem about?

A~tract--The solution of the mode-I crack problem is given by using an anisotropic straingradient elasticity theory with surface energy, extending previous results by Vardoulakis and coworkers, as well as by Aifantis and co-workers. The solution of the problem is derived by applying the Fourier transform technique and the theory of dual integral and Fredholm integral equations. Asymptotic analysis of the solution close to the tip gives a cusping crack with zero slope of the crack displacement at the crack tip. Cusping of the crack tips is caused by the action of "cohesive" double forces behind and very close to the tips, that tend to bring the two opposite crack lips in close contact. Consideration of Griflith's energy balance approach leads to the formulation of a fracture criterion that predicts a linear dependence of the specific fracture surface energy on increment of crack propagation for such crack length increments that are comparable with the characteristic size of material's microstructure. This important theoretical result agrees with experimental measurements of the fracture energy dissipation rate during fracturing of polycrystalline, polyphase materials such as rocks a
