Stress Intensity Factor Variation along a Semicircular Surface Flaw in a Finite-thickness Plate
-The stress intensity factor variation along a semicircular surface law in a three dimensional solid @late) of finite thickness is derived. This is done using a nested alternating procedure which employs the complete analytical solution for an arbitrarily loaded circular flaw embedded in an infinite solid. The method accounts for both the front-surface/backsurface as well as the boundary-crack ...
متن کاملAccurate Determination of Stress Intensity Factor for Interface Crack by Finite Element Method
This paper presents the simple method to determine the complex stress intensity factor of interface crack problem by the finite element method. The proportional method is extended to the interface crack problem. In the present method, the stress values at the crack tip calculated by FEM are used and the stress intensity factors of interface crack are evaluated from the ratio of stress values be...
متن کاملStress intensity factors for a crack in front of an inclusion
A stable numerical algorithm is presented for an elastostatic problem involving a crack close to and in front of an inclusion interface. The algorithm is adaptive and based on an integral equation of Fredholm’s second kind. This enables accurate analysis also of rather difficult situations. Comparison with stress intensity factors of cracks close to straight infinite bimaterial interfaces are m...
متن کاملShear Stress Intensity Factors for a Planar Crack With Slightly Curved Front
Recent work (Rice, 1985a) has presented the calculations of the first order variation in an elastic displacement field associated with arbitrary incremental planar advance of the location of the front of a half-plane crack in a loaded elastic full space. That work also indicated the relation of such calculations to a three-dimensional weight function theory for crack analysis and derived an exp...
متن کاملMultigrid Methods for the Computation of Singular Solutions and Stress Intensity Factors Ii: Crack Singularities
We consider the Poisson equation ?u = f with homogeneous Dirichlet boundary condition on a two-dimensional polygonal domain with cracks. Multigrid methods for the computation of singular solutions and stress intensity factors using piecewise linear functions are analyzed. The convergence rate for the stress intensity factors is
