Crack arrest testing at the micro-scale

Engineering Fracture Mechanics, 2018
Abstract Crack arrest testing of micro-sized cantilever beams (≈8 × 4 × 6 μm, length, width and height, respectively) was conducted in order to evaluate the suitability of a new method to quantify local crack arrest properties. Chevron notched cantilevers were milled to match the (1 0 0)[0  1 ¯  1] crack system in α-iron, where earlier ...

A hybrid micro–macro BEM formulation for micro‐crack clusters in elastic components

International Journal for Numerical Methods in Engineering, 1995
AbstractLocal analysis schemes capable of detailed representations of the micro‐features of a problem are integrated with a macro‐scale BEM technique capable of handling complex finite geometries and realistic boundary conditions. The micro‐scale effects are introduced into the macro‐scale BEM analysis through an augmented fundamental solution obtained

Micro-textural effects on crack initiation and crack propagation of andesitic rocks

Engineering Geology, 2015
Abstract The onset of dilation and uniaxial compressive strength (UCS) of rocks are known to be affected by mineralogical, petrographic and microstructural features. Therefore micro-textural variations are essential for understanding variation in strength and failure behaviour of rocks.

Micro-facets of crack surfaces in metals

International Journal of Fracture Mechanics, 1968
Recent experiments involving the study of crack contours and neighbouring regions in the electron microscope are analyzed. The present work represents an extension of previous investigations on the crystallography of separation. The materials studied are a carbon steel, two austenitic stainless steels, zirconium and zinc.
