Abstract:

A joint dislocation, or luxation occurs when there is an abnormal separation in the joint, where two or more bones meet. A partial dislocation is referred to as a subluxation. Dislocations are often caused by sudden trauma on the joint like an impact or fall. A joint dislocation can cause damage to the surrounding ligaments, tendons, muscles, and nerves Dislocations can occur in any joint major (shoulder, knees, etc.) or minor (toes, fingers, etc.). The most common joint dislocation is a shoulder dislocation. Symptoms: intense pain, joint instability, deformity of the joint area, reduced muscl

La dynamique des dislocations discrètes (DDD) a été appliquée pour examiner les effets des précipités sur la plasticité des monocristaux de structure CFC. Les précipités sont modélisés par un assemblage de facettes franchissable pour une contrainte donnée. Afin de tenir compte des interactions élastiques entre les dislocations et les particules, un couplage avec la méthode des éléments finis (MEF) a été utilisé. Afin d'accélérer les temps de calculs, la 'méthode des boites' a été revisitée et une version parallèle du code a été développée en utilisant le standard du programmation 'Message Pass

Abstract:

Work-hardened metals typically possess large numbers of dislocations in complex three-dimensional configurations about which little is known theoretically. Here these large numbers of dislocations are accounted for by means of a dislocation density tensor, which is obtained by applying an averaging process to families of discrete dislocations. Some simple continuous distributions are examined and an analogy is drawn with solenoids in electromagnetism before the question of the equilibrium of dislocation configurations is studied. It is then proved that the only finite, simply-connected distrib

Abstract:

Understanding the molecular basis of Mendelian disorders featuring joint dislocation can enhance the knowledge of genetic or cellular pathways required in joint development, and provide candidate genes for studying related complex disorders, such as developmental dysplasia of the hip. Two strategies were employed in this project to investigate Mendelian contributors to congenital joint dislocation. The first strategy was to investigate in-depth a gene known to be associated with joint dislocation. Missense mutations or small in-frame deletions in FLNB, encoding filamin B, have previously bee

Irradiation induced void swelling is problematic for the application of austenitic steels under high dose irradiation. In this thesis, the swelling is characterized by dislocation bias. The dislocation bias is obtained using the finite element method, accounting for fcc copper and nickel under electron irradiation. The methodology is implemented with the interaction energies between an edge dislocation and point defects. Analytically derived interaction energies, which are based on elasticity theory, are compared with interaction energies obtained from atomistic model using semi-empirical atom

Polycrystal models, beginning with the work of Sachs (1928) and Taylor (1938), have been used to predict very complex material behavior. The basis of these models is single crystal plasticity theory, which is then extended to model an actual (polycrystalline) material composed of a large number of single crystals or grains. Crystal plasticity models are formulated at the scale of the individual grain, which is viewed as a fundamental material element. To first order this is a reasonable approximation, and results in qualitatively good predictions. However, it is also well known that the grain

Abstract:

Thesis (Ph.D.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering, 2001.<br>Includes bibliographical references (p. 221-229).<br>Dislocations are the singly most important material defects in crystal plasticity, and although dislocation mechanics has long been understood as the underlying physical basis for continuum crystal plasticity formulations, explicit consideration of crystallo- graphic dislocation mechanics has been largely absent in working constitutive models. In light of recent theoretical developments in dislocation dynamics, and the introduc- tion of geometric
