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...

Towards the treatment of boundary conditions for global crack path tracking in three-dimensional brittle fracture

The aim of the present paper is a systematic elab1 oration of a three dimensional finite element analysis tool for 2 discontinuous fracture in brittle solids. Brittle or quasi-brittle 3 fracture usually occurs when a material reaches the limit of its 4 strength and no plastic deformation has been observed prior 5 to failure. In the present approach, this kind of failure is char6 acterized by th...

An Einstein Model of Brittle Crack Propagation

We propose a minimal nonlinear model of brittle crack propagation by considering only the motion of the crack-tip atom. The model captures many essential features of steady-state crack velocity and is in excellent quantitative agreement with many-body dynamical simulations. The model exhibits lattice-trapping. For loads just above this, the crack velocity rises sharply, reaching a limiting valu...
