Mixed Mode Fracture Analysis of Multiple Interface Cracks

This paper contains a theoretical formulation of multiple interface cracks in two bonded dissimilar half planes subjected to in-plane traction. The distributed dislocation technique is used to construct integral equations for a dissimilar mediums weakened by several interface cracks. These equations are of Cauchy singular type at the location of dislocation, which are solved numerically to obta...

A Plasticity Criterion for Mixed Mode Fracture Initiation with Crack Surface Frictional Characteristics Under Compression

A new plasticity criterion for mixed mode crack initiation angles under compression is presented, based on the characteristics of the plastic core region surrounding the crack tip with crack surface friction. The shape and size of the plastic core region were thoroughly analyzed under compression and the non-dimensional variable radius of the plastic core region for mixed mode compressive fract...

experimental study of furfurylation effect on fracture of beech wood under mixed mode

fracture of mixed mode i/ii in beech wood and its wood polymers has been investigated experimentally in this study. hence, two crack systems of tl and rl were selected in which the crack planes extend along the wood fibers. this investigation has demonstrated that onset of mixed mode cracking can be predicted with a very simple fracture criterion in these crack systems. results indicated that f...

Isotopic Resonance Hypothesis: Experimental Verification by Escherichia coli Growth Measurements

Isotopic composition of reactants affects the rates of chemical and biochemical reactions. As a rule, enrichment of heavy stable isotopes leads to progressively slower reactions. But the recent isotopic resonance hypothesis suggests that the dependence of the reaction rate upon the enrichment degree is not monotonous. Instead, at some "resonance" isotopic compositions, the kinetics increases, w...

Mixed-mode fracture of human cortical bone.

Although the mode I (tensile opening) fracture toughness has been the focus of most fracture mechanics studies of human cortical bone, bones in vivo are invariably loaded multiaxially. Consequently, an understanding of mixed-mode fracture is necessary to determine whether a mode I fracture toughness test provides the appropriate information to accurately quantify fracture risk. In this study, w...
