Effect of Residual Stress on Brittle Fracture Testing
Residual stress present in coupons used for fracture testing will influence the experimental determination of fracture toughness. Triaxial residual stress (e.g., due to welding) can alter both the driving force for fracture and the crack-tip constraint at a specified load, so that the apparent toughness of a coupon depends on the residual stress present. In this paper, we employ a micromechanic...
متن کاملFractal 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...
متن کاملCrack 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...
متن کاملBrittle 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.
متن کاملBrittle 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...
