The Part-Through Surface Crack in an Elastic Plate
An elastic analysis is presented for the tensile stretching and bending of a plate containing a surface crack penetrating part-through the thickness, Fig. 1. The treatment is approximate, in that the two-dimensional generalized plane stress and KirchhoffPoisson plate bending theories are employed, with the part-through cracked section represented as a continuous line spring. The spring has both...
متن کاملSTRESS INTENSITY FACTORS FOR AN INTERIOR GRIFFITH CRACK OPENED BY HEATED WEDGE IN A STRIP WHOSE EDGES ARE NORMAL TO CRACK AXIS
After second world war, we have seen a very rapid development of Thermoelasticity stimulated by various engineering sciences. As we know, structures behave in different fashion under climate variation and the most responsible factor for these variations is heat which falls through and causes deformation of the body. A considerable progress in the field of aircraft and machine structures, mainly...
متن کاملImproved Formula for the Stress Intensity Factor of Semi-Elliptical Surface Cracks in Welded Joints under Bending Stress
Welded joints are prone to fatigue cracking with the existence of welding defects and bending stress. Fracture mechanics is a useful approach in which the fatigue life of the welded joint can be predicted. The key challenge of such predictions using fracture mechanics is how to accurately calculate the stress intensity factor (SIF). An empirical formula for calculating the SIF of welded joints ...
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 کاملFracture Analysis of Externally Semi-Elliptical Crack in a Spherical Pressure Vessel with Hoop-Wrapped Composite
In this paper the effect of composite hoop-wrapped on stress intensity factor for semi-elliptical external crack which located in spherical pressure vessel, were investigated through the Finite Element Analysis. In order to find the effect of some parameters such as composite thickness and width, internal pressure and crack geometry, comparisons between different cases were done and discussed i...
