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...
متن کاملMixed-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...
متن کاملComparison of Different Methods of Evaluation of Weight Functions for 2-d Mixed-mode Fracture Analyses
In this paper, two different techniques for mixed-mode type engineering fracture analysis, by using the weight-function method, are presented. These two methods are (a) the virtual crack extension technique (VCE), and (b) the equivalent domain integral method (EDI). For mixed-mode weight-function evaluation, a technique of using two reference load states, both of which cannot be either pure mod...
متن کاملInvestigation of mixed-mode dynamic fracture in syntactic foams using digital image correlation method and high-speed photography
In this work, a combination of digital image correlation and high-speed photography is used to study mixed-mode dynamic fracture in syntactic foams under stress wave loading conditions. Edge cracked foam samples are subjected to mixed mode loading by impacting eccentrically relative to the initial crack plane in three point bend configuration. Ultra high-speed CCD digital camera is used to reco...
متن کاملFinite Element Modeling of Crack Initiation Angle Under Mixed Mode (I/II) Fracture
Present study deals with the prediction of crack initiation angle for mixed mode (I/II) fracture using finite element techniques and J-Integral based approach. The FE code ANSYS is used to estimate the stress intensity factor numerically. The estimated values of SIF were incorporated into six different crack initiation angle criteria to predict the crack initiation angle. Single edge crack spec...
