Nonequilibrium brittle fracture propagation: Steady state, oscillations, and intermittency.

A minimal model is constructed for two-dimensional fracture propagation. The heterogeneous process zone is presumed to suppress stress relaxation rate, leading to non-quasistatic behavior. Using the Yoffe solution , I construct and solve a dynamical equation for the tip stress. I discuss a generic tip velocity response to local stress and find that noise-free propagation is either at steady sta...

Fractal Dimension of Brittle Fracture

Using a worldwide catalog of earthquakes we analyze the distribution of distances between pairs of earthquake hypocenters to determine the spatial fractal dimension 6 of an earthquake fracture. As the time span of the catalog increases, 8 asymptotically reaches the value 2.1-2.2 for shallow earthquakes. Approximately the same asymptotic value of dimension is obtained for a catalog of earthquake...

Brittle Fracture of 2D MoSe2.

An in situ quantitative tensile testing platform is developed to enable the uniform in-plane loading of a freestanding membrane of 2D materials inside a scanning electron microscope. The in situ tensile testing reveals the brittle fracture of large-area MoSe2 crystals and measures their fracture strength for the first time.

Brittle fracture of dental amalgam.

The brittleness of dental amalgam limits its use to sites in which tensile stresses can be kept at a minimum. If the cause for the brittleness could be ascertained, then an approach to correct this problem could be devised. Physical properties of metals are ultimately manifested in, and can be explained by, their microstructure. Through the work of several researchers,1-3 means of identifying t...

Crack Growth during Brittle Fracture

Title: Crack Growth During Brittle Fracture in Compression. Author: Bartlett W. Paulding, Jr. Submitted to the Department of Geology and Geophysics February 9, 1965 in partial fulfillment of the requirements for the degree of Doctor of Philosophy at the Massachusetts Institute of Technology. Photoelastic analysis of several two-crack arrays predicts that compressive fracture is initiated at cra...
