Crack initiation in elastic bodies
In this paper we study the crack initiation in a hyper-elastic body governed by a Gri th's type energy. We prove that, during a load process through a time dependent boundary datum of the type t→ tg(x) and in absence of strong singularities (this is the case of homogeneous isotropic materials) the crack initiation is brutal, i.e., a big crack appears after a positive time ti > 0. On the contrar...

متن کاملWave Propagation in an Elastic Solid with a Line of Discontinuity or Finite Crack*
With the aid of integral transforms, a method is presented for solving the problem of scattering of plane harmonic compression and shear waves by a line of discontinuity or crack of finite width embedded in an elastic medium of infinite extent. When the incoming waves are applied in an arbitrary direction, the scattered-wave field may be determined by separating the crack-surface boundary condi...
متن کاملThree-dimensional Perturbation Solution for a Dynamic Planar Crack Moving Unsteadily in a Model Elastic Solid
A HALF-PLANE CRACK propagates dynamically, nominally in the x direction. along the plane _V = 0 in an unbounded solid subjected to remote loading equivalent to a static stress intensity factor K*. The crack front at time t lies along the arc x = c,,t+a_/‘(z, t) where a,) is a constant velocity, J’(z, t) is an arbitrary function, and E is a small parameter. The crack front speed thus varies alon...
متن کاملPropagation of Crack in Linear Elastic Materials with Considering Crack Path Correction Factor
Modeling of crack propagation by a finite element method under mixed mode conditions is of prime importance in the fracture mechanics. This article describes an application of finite element method to the analysis of mixed mode crack growth in linear elastic fracture mechanics. Crack - growth process is simulated by an incremental crack-extension analysis based on the maximum principal stress c...
