In this paper, influence of riveting process parameters, namely, riveting force, sheet thickness, friction coefficient and clearance fit are investigated on residual stress field and fatigue life of single riveted lap joint of AA2024 type. According to the effect of riveting induced residual stresses on fatigue life of riveted lap joint, these parameters are optimized to maximize the residual s...

The fatigue growth of multiple cracks, of arbitrary lengths, emanating from a row of fastener holes in a bonded, riveted, lap joint in a pressurized aircraft fuselage is studied. The effects of residual stresses due to a rivet misfit, and of plastic deformation near the hole, are included. A Schwartz Neumann alternating method which uses the analytical solution for a row of multiple colinear cr...

In the last years haplotype reconstruction and haplotype blocks discovery, i.e., the estimation of patterns of linkage disequilibrium (LD) in the haplotypes, riveted the attention of the computer scientists due to the involved strong computational aspects. Such tasks are usually faced separately; recently, statistical generative techniques permitted to solve them jointly. Following this trend, ...

Sitting in our offices early in the morning of September 11, 2001, we, like many across the world, watched with incredulity the twin terrorist strikes on the World Trade Centre. Riveted to the television screen, we witnessed the beginnings of a nightmare whose images will likely remain with us for a long time. September 11, and the events that followed, changed our assumptions of world terroris...

Quadrilateral shaped brims made of high-density polyethylene have been used with satisfactory results on more than 120 patients who needed ischial-bearing long leg calipers. At first the fitting technique was the same as that used for thigh amputees. Subsequently it has been possible to fit most patients from a range of pre-formed brims. The properties of high-density polyethylene allow the cal...
