Objective: Femur is the strongest, longest and heaviest bone in the human body. Due to the great importance of femur in human body, its injury may cause large numbers of disabilities and mortality. Considering various effective parameters such as mechanical properties, geometry, loading configuration, etc. can propel the study to the trustable results.. Methods: A 3D finite element model of the...

to investigate the effect of tempering treatment on mechanical properties and the microstructure ofdin 1.4021 martensitic stainless steel, austenite treatment was conducted for the samples at 1000ºc temperature for 60 min and then the samples were oil quenched. later, tempering treatments wereperformed for the samples at 500 ºc and 700 ºc temperatures for 2 and 5 h, respectively; then quenching...

Fibre metal laminates (FMLs) have appeared as the most suitable materials for shipbuilding, aeronautical and aerospace applications due to their superior mechanical properties over traditional materials. In this paper, degradation in flexural and impact properties of glass fibre/epoxy composite (GF/E composite) and stainless steel glass fibre/epoxy fibre metal laminate (SS FML) due to hygrother...

the chemical composition and uniform distribution of alloying elements in the matrix of austempered ductile irons (adis) have significant influences on their properties, e.g. segregation of the alloying elements have detrimental effects on the mechanical properties of these materials. unlike previous studies, the homogenization treatment via partial melting was used in this study in order to re...

Introduction: Subchondral bone (SB) micro-fracture due to high-impact loading is a key factor leading to post traumatic knee osteoarthritis [1]. The apparent-level impact mechanics of SB has been previously investigated using mechanical tests [2]. However, to investigate the osteochondral injuries, the tissue-level impact mechanics, especifically, the mechanical parameters associated with SB mi...

Various applications of nanocomposites were a good motivation to start a study on this wide spreading field of science. Current research is an investigation on incorporating different percentages of TiO2 nanoparticle as reinforcement to a base material which here is poly methyl methacrylate (PMMA). In this study various percentages of TiO2 (0.5, 1 and 2 wt%) were added to pure PMMA and effect o...
