With advanced composites increasing replacing traditional metallic materials, the material inhomogeneity and inherent anisotropy of such materials lead to not only new attributes for aerospace structures, but also introduce new technology to damage tolerant design and analysis. The deleterious effects of changes in material properties and initiation and growth of structural damage must be addre...

This paper describes finite element simulations of the structural deformation and material fracture behaviour high-strength steel RHS K gap truss joints. The fundamental scope was to examine whether joint strength predictions based on lower more ductile with a yield stress 355 MPa or less would hold good for higher 450 ductility. FEA reliability analysis indicates that failure modes associated ...

The use of functional repair components stored inside hollow reinforcing fibres is being considered as a self-repair system for future composite structures. The incorporation of a self-healing capability within a variety of materials, including fibre reinforced polymers (FRPs), has been investigated by a number of workers previously. This paper considers the placement of self-healing plies with...

OBJECTIVES We assessed whether grip strength was related to various types of radiographic damage in Korean adults with osteoarthritis (OA). METHODS Data from 2,251 subjects enrolled in the Dong-gu study, who had no hand joint pain, were analyzed to investigate the relationship between grip strength and OA. Hand grip strength was measured using a hand-held dynamometer, and radiographs of the h...
