The fatigue life of tubular joints commonly found in offshore industry is not only dependent on the value of hot-spot stress (HSS), but is also significantly influenced by the through-thethickness stress distribution characterized by the degree of bending (DoB). The determination of DoB values in a tubular joint is essential for improving the accuracy of fatigue life estimation using the stress...

Our understanding of the evolution of frog locomotion follows from the work of Emerson in which anurans are proposed to possess one of three different iliosacral configurations: 1) a lateral-bending system found in walking and hopping frogs; 2) a fore-aft sliding mechanism found in several locomotor modes; and 3) a sagittal-hinge-type pelvis posited to be related to long-distance jumping perfor...

Mechanics models are developed for an imbricate scale design for stretchable and flexible electronics to achieve both mechanical stretchability and high fill factors (e.g., full, 100% areal coverage). The critical conditions for self collapse of scales and scale contact give analytically the maximum and minimum widths of scales, which are important to the scale design. The maximum strain in sca...

in his paper the effect of ribbing in bending and tortional resisance of the box type structure is discussed . for satisfactory design of press structures . the stiffness characteristics of individual components are recognised to be of primary importance. heavy press stucures are normaly constructed in double-sided form . because of transportation and handing problems , these frames are usually...

Please cite this article in press as: Xiong J et al. M doi:10.1016/j.matdes.2010.08.016 A new type of lightweight sandwich panels consisting of vertically aligned hollow Al–Si alloy tubes as core construction and carbon fiber composite face sheets was designed. The hollow Al–Si alloy tubes were fabricated using precision casting and were bonded to the face sheets using an epoxy adhesive. The ou...
