Effective elastic moduli in solids with high density of cracks
We investigate the weakening of elastic materials through randomly distributed circles and cracks numerically and compare the results to predictions from homogenization theories. We find a good agreement for the case of randomly oriented cracks of equal length in an isotropic plane-strain medium for lower crack densities; for higher densities the material is weaker than predicted due to precurs...
متن کاملEffective elastic moduli of two dimensional solids with distributed cohesive microcracks
Effective elastic properties of a defected solid with distributed cohesive micro-cracks are estimated based on homogenization of the Dugdale–Bilby–Cottrell–Swinden (Dugdale–BCS) type micro-cracks in a two dimensional elastic representative volume element (RVE). Since the cohesive micro-crack model mimics various realistic bond forces at micro-scale, a statistical average of cohesive defects can...
متن کاملGuided Waves Along Fluid-Filled Cracks in Elastic Solids and Instability at High Flow Rates
We characterize wave propagation along an infinitely long crack or conduit in an elastic solid containing a compressible, viscous fluid. Fluid flow is described by quasi-onedimensional mass and momentum balance equations with a barotropic equation of state, and the wall shear stress is written as a general function of width-averaged velocity, density, and conduit width. Our analysis focuses on ...
متن کاملElastic wave propagation and scattering in solids with uniaxially aligned cracks.
In this article, elastic wave propagation and scattering in a solid medium permeated by uniaxially aligned penny-shaped microcracks are studied. The crack alignment refers to the case in which the unit normals of all cracks are randomly oriented within a plane of isotropy. The analysis is restricted to the limit of the noninteraction approximation among individual cracks. Explicit expressions f...
متن کاملOn Effective Moduli of an Elastic Body Containing Periodically
D*kiauaki = Dijkiauaki + /°,% (4) which is Eq. (4.4) of [1], where / is the volume fraction of voids. The average transformation strain, e*, in (4) must, however, be obtained for the case when the stresses (and not the strains) are regarded to be prescribed. Therefore, in the integral equation (2.13) of [1], ek/ must be replaced by ek/ defined by (2) above, if Eq. (4) is used to calculate D*. F...
