Vast experiments have demonstrated that the external specimen size makes a large difference in the deformation behavior of crystalline materials. However, as one important kind of internal planar defects, the role of grain boundary (GB) in small scales needs to be clarified in light of the scarce and inconsistent experimental results at present. Through compression of Cu bicrystal and its count...

A survey was conducted of 192 work-hardening and work-adjustment programs to gain an overview of practice patterns. The questionnaire covered program affiliation, services offered, staffing, program scheduling, average length of treatment per client, equipment used, physical settings, program status, number of clients seen each week, and types of functional outcome studies and research. The res...

The paper aims at studying the dislocation nucleation, the corresponding work hardening and the influence of resistance to the dislocation motion within the framework of continuum theory of dislocations. We consider an anti-plane constrained shear problem which admits an analytical solution. The interesting features of this solution are the energy and dissipation thresholds for dislocation nucl...

V-Band Clamps are manufactured using a cold roll forming process consisting of six passes which plastically deform an initially flat strip by bending to produce the band’s V-section. In this paper a new method of validating numerically predicted plastic deformation in a cold formed metal strip is presented. Tensile testing of samples of the band’s material was used to obtain a direct link betwe...

The rehabilitation of this client with chronic back pain was successful secondary to the efforts of her entire medical team. As demonstrated by the termination letter written by the employer when the client's medical leave exceeded 1 year, this client could not have returned to her former position without work hardening. With implementation of the Americans With Disabilities Act, changes in suc...

The American.!oumal of' Occupational FhemjJ)' W ork.hardening concepts and techniques originated in occupational therapy (West & McNary, 1956). Occupational therapy's use of activity as a primary modality and its activity analysis of the phYSical and psychosocial components of an occupation substantiate its involvement in work-hardening programs (Harvey-Krefting, 1985). The profession's philoso...
