Crack deflection 意味
WebThe coordinates can also be used to determine the plane or facet orientation, profile or surface fractal dimension, and the crack profile deflection angles. A mechanics of materials model which predicts the fracture toughness increase due to crack deflection around second phase particles in a matrix was proposed by Faber and Evans [3]. http://www.yyfangchan.com/jlfanwen/638605.html

WebCrack deflection occurs mainly at the phase boundaries, but crack branching occurs mainly in the grains due to the dislocation slip. In-situ SEM/EBSD fatigue test confirms that crack propagation deflection can lead to a decrease in crack propagation rate. Formation of crack branches can significantly reduce the crack propagation rate, which can ... WebSection: Crack Deflection mentioning. confidence: 99%. “…This causes an increase in the total fracture surface area and also causes the crack to grow locally under mixed-mode I/II conditions. The former toughening effect can be evaluated by (i) comparing the measured fracture toughness with the surface roughness, and (ii) the latter ...
WebOne of the prerequisites for crack deflection to occur in fiber reinforced composites is a high elastic modulus mismatch between reinforcement and matrix, as the Dundurs … Webmonolithic ceramics result from crack deflection and propaga-tion that occur at weak interfaces or within weak interphases between the strong layers. Although several models exist that predict the conditions under which crack deflection should oc-cur,8–10 there is not much experimental data on all-ceramic systems to support these models.
