the problem of several finite moving cracks in a functionally graded material is solved by dislocation technique under the condition of anti-plane deformation. by using the fourier transform the stress fields are obtained for a functionallygraded strip containing a screw dislocation. the stress components reveal the familiar cauchy singularity at thelocation of dislocation. the solution is empl...

simultaneous dislocation of both interphalangeal (ip) joints of same finger is a highly uncommon finding. and dislocation of metacarpophalangeal (mcp) joint along with interphalangeal joints of thumb are reported in literatures if, scarcely. here we are reporting the three cases, comprising of double dislocation of ip joints in little finger in two patients and simultaneous mcp and ip joint dis...

Background:  The glenohumeral joint becomes dislocated more than any other major joint because it maintains a wide range of motion and its stability is inherently weak. The most common complication following acute initial shoulder dislocation is recurrent dislocation or chronic instability. Imbalance of strength and range of motion in individuals with anterior dislocation can be a contributing ...

Aging of precipitation hardened alloys results in particle coarsening, which in turn affects the strength. In this study, the effect of particle size distribution on the strength of precipitation-hardened alloys was considered. To better represent real alloys, the particle radii were distributed using the Wagner and Lifshitz and Slyozov (WLS) particle size distribution theory. The dislocation m...

Nondestructive measurements of the full elastic strain and stress tensors from individual dislocation cells distributed along the full extent of a 50 µm-long polycrystalline copper via in Si is reported. Determining all of the components of these tensors from sub-micrometre regions within deformed metals presents considerable challenges. The primary issues are ensuring that different diffractio...

background appropriate treatment of acromioclavicular joint dislocation is controversial. acroplate fixation is one of the most common treatment methods of acromioclavicular joint (acj) dislocation. based on the risk of re-dislocation after acroplate fixation, we assumed that combined fixation with an acroplate and a coracoclavicular screw helps improve the outcome. objectives the main purpose ...

We study consistent collections of random fragmentation trees with random integervalued edge lengths. We prove several equivalent necessary and sufficient conditions under which Geometrically distributed edge lengths can be consistently assigned to a Markov branching tree. Among these conditions is a characterization by a unique probability measure, which plays a role similar to the dislocation...

In the past 100 years, precipitation strengthening has always been extremely important pathway to resist deformation of material due significantly improving matrix strength. The size deviation degree and space distribution precipitates have a great influence on strength reported by recent experiments, however, this internal mechanism largely ignored incompletely understood until now in nickel-b...
