Simple shear of a constrained strip is analyzed using both discrete dislocation plasticity and strain gradient crystal plasticity theory. Both single slip and symmetric double slip are considered. The loading is such that for a local continuum description of plastic flow the deformation state is one of homogeneous shear. In the discrete dislocation formulation the dislocations are all of edge c...

Abstract: The solution to problem of an orthotropic long cylinder subjected to torsional loading is first obtained by means of separation valuables. The cylinder is twisted by two lateral shear tractions and the ends of the cylinder surface of the cylinder are stress-free. First, the domain under consideration is weakened by an axisymmetric rotational Somigliana ring dislocation. The dislocatio...

Introduction & Objective: Shoulder joint is the most common articular dislocations in the body. There are many surgical techniques for the treatment of recurrent shoulder dislocation. The aim of the study is to evaluate the short-term results of surgical technique of modified Bankart repair for recurrent anterior shoulder instability. Materials & Methods: Twenty patients underwent an operati...

PURPOSE Dislocation of the mesh is 1 cause of recurrence after laparoscopic inguinal hernia repair (LIHR). Here, we propose a new procedure, the "preperitoneal cavity suction technique," to confirm mesh position during LIHR under a transabdominal preperitoneal approach (TAPP). PATIENTS AND METHODS We developed the "preperitoneal cavity suction technique" during LIHR by TAPP, visualizing the m...

Urgent development of alternative on-farm killing methods for poultry is required following the number restrictions placed on the use of traditional manual cervical dislocation by European Legislation (EU 1099/2009). Alternatives must be proven to be humane and, crucially, practical in commercial settings with multiple users. We assessed the performance and reliability of a novel mechanical cer...

Diffraction-contrast electron tomography was used to analyse the 3D geometry of dislocation microstructure in a zirconium alloy before and after ion irradiation. The material had been strained at room temperature prior After straining, exhibited mainly screw dislocations with Burgers vectors. From analysis habit plane non-screw segments, it deduced that they have glided prismatic planes les...

Locked posterior shoulder dislocation is an uncommon condition and is associated with a reverse Hill-Sachs lesion in 50% of cases. The condition is likely to occur in cases of violent trauma, seizures, or electric shock. Unrecognized dislocation with humeral head fracture affects joint function and humeral head vascularity and may lead to chronic instability, osteonecrosis, and osteoarthritis. ...
