Finite element analyses (FEA) are flexible and advanced approaches, which utilized to address difficult problems of aerospace materials that exhibit both structural symmetrical asymmetrical characteristics. Frictional behavior effects used as a crucial in this multidisciplinary study, other structural, thermal properties computed using FEA. Primary lightweight such glass fiber reinforced polyme...
Bone plates are essential for bone fracture healing because they modify the biomechanical microenvironment at site to provide necessary mechanical fixation fragments. This paper addresses use of composite in long-bone fractures such as transverse femur. However, stress shielding due metal can be reduced by designing implants with Bio-composites that involve Ultra high molecular polyethylene rei...
Motivated by the high level of strength and toughness of spider silk and its multifunctional nature, this paper reports on the engineering properties of individual fibers from Nephila Clavipes spider drag line under uniaxial tension, transverse compression and torsional deformation. The tensile properties were compared to the Argiope Aurentia spider silk and show different ultimate strength but...
Measurements are reported for the compressive response of ultra-high molecular weight polyethylene (UHMWPE) fibres and laminated composites loaded along the fibre direction. The compressive strength of the fibres was measured by both recoil tests and knot (or bend) tests. The strength of the fibres is governed by micro-kinking of the fibrils within the fibres. The recoil tests suggest that this...
The Birnbaum–Saunders (BS) distribution, well-known as the fatigue-life has been used in numerous disciplines ranging from engineering to medical sciences. In this article, we develop a test for analysis of medians BS distributed response assess impact two interacting factors on median, where no is presently available. proposed integrated likelihood ratio (ILRT) eliminates nuisance shape parame...
