Box-like Shells with Longitudinal Cracks

2009
The problem of how to determine the stress state of an infinite box-like shell of rectangular profile is solved. Two cracks are located on opposite sides of the shell and parallel to its edges. On applying a Fourier transform, the problem can be reduced to a system of two integral equations with respect to jumps at the corner of rotation and normal ...

Longitudinal vibration of a continuous cracked bar

Engineering Fracture Mechanics, 1998
Abstract A continuous cracked bar vibration theory is developed for longitudinal vibration of rods with an edge crack. The Hu–Washizu–Barr variational formulation was used to develop the differential equation and the boundary conditions of the cracked bar as a one-dimensional continuum.

External cracks under longitudinal shear

Journal of the Franklin Institute, 1965
Abstract The theory of cracks under longitudinal shear, as discussed in previous publications (1, 2, 3), is extended to bodies containing external cracks. It is possible, by an adaptation of the Schwartz-Christofel transformation, to derive a general formula for finding the stress-intensity factor, a parameter governing the onset of rapid fracture in

Longitudinal vibration of a bar with a breathing crack

Engineering Fracture Mechanics, 1998
Abstract The dynamics of a cracked fixed-free bar with a breathing crack in longitudinal vibration is investigated. The Hu–Washizu–Barr variational formulation was used to develop the equation of motion and the boundary conditions of the cracked bar as a one-dimensional continuum.

Longitudinal Crack Propagation in Bone Around Femoral Prosthesis

Clinical Orthopaedics and Related Research, 1991
Intraoperative femoral fracture is a well-recognized technical complication of cementless total hip arthroplasty. This study was designed to establish an in vitro model for initiation and propagation of fractures of the proximal femur in cementless THA and to assess the effect of fracture fixation in the form of cerclage wiring and drilling a hole in ...

Analysis of Longitudinal Cracks in Road Embankments

2013
One of the most adverse types of pathology in road embankments is the longitudinal cracks. As the cracks appear in a random way, the understanding of the causes leading to the formation and evolution of the cracks and the specification of measures to reduce their occurrence becomes a major challenge.

Secondary crack trajectory for longitudinal shear problems

International Journal of Fracture Mechanics, 1970
In some practical problems the direction of crack growth is not colinear with the orientation of the pre-existing and unloaded crack. The longitudinal shear loading is one for which an analytical solution can be exploited and the strain energy variation with respect to relative orientation can be evaluated.

Unsteady propagation of longitudinal shear cracks

Journal of Applied Mathematics and Mechanics, 1966
Abstract In all problems of unsteady crack propagation which have been solved to date [1 to 3], it has been assumed that the crack propagates at a constant speed. This assumption was not prompted by physical considerations of the problem, but by the methods of solution, therefore, the applicability of the results is limited.

Interaction of torsion waves with longitudinal cracks in tubes

Russian Journal of Nondestructive Testing, 2006
A testing method, theoretical and experimental studies of velocity, damping, and reflection of a torsion wave in a tube with a modeled longitudinal crack are discussed. The considered results can be regarded as a basis for the development of effective methods and means that use torsion waves to test acoustic tubes.

Longitudinal tooth cracks and fractures: an update and review

Endodontic Topics, 2015
The purpose of this updated review is to further discuss the diagnostic and treatment challenges related to tooth cracks and fractures that occur primarily in the vertical plane, that is, the long axis of the crown and/or root. This includes when and how to identify and determine the category and the extent of the fracture, when a coronally reinforcing
