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 کاملThe effect of crack surface interaction on the stress intensity factor in Mode III crack growth in round shafts
Turbine-generator shafts are often subjected to a complex transient torsional loading. Such transient torques may initiate and propagate a circumferential crack in the shafts. Mode III crack growth in turbo-generator shafts often results in a fracture surface morphology resembling a factory roof. The interaction of the mutual fracture surfaces results in a pressure and a frictional stress field...
متن کاملA finite element alternating method for evaluation of stress intensity factors fpr part-circular cracks subjected to arbitrary loadings
The stress intensity factor solution for embedded circular cracks, semicircular and part-circular surface cracks in plates, quartercircular corner cracks in rods, and semicircular surface cracks at a hole in a plate are evaluated using a finite element alternating method. This method of superposition employs the standard 20-noded solid element solution for the untracked solid, and the complete ...

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...
