Contact mechanics is a topic that performs the investigation of the deformation of solids that touch each other at one or more points. A principal distinction in contact mechanics is between stresses acting perpendicular to the contacting bodies' surfaces and stresses acting tangentially between the surfaces. This study focuses mainly on the normal stresses that are caused by applied forces.

The computational model shows that plastic buckling of cells with progressive plasticity of the contact area is the key local failure mechanism. As expected, due to the plastic buckling of the unit cells, thermal degradations of the tested metallic foams follow similar trends as does the yield stress of their bulk metals.

The investigation analyzes effects of clearance size in revolute and spherical joints with clearance on rigid-flexible dynamic of a space slider crank mechanism by finite element method. The model of the mechanism was designed by Solidworks and then velocity, acceleration, displacement, stress and contact force were determined by finite element analysis of rigid-transient dynamic in ANSYS.

Chronic ankle instability (CAI) arises from the two etiological factors of functional (FAI) and mechanical ankle instability (MAI). To distinguish the contributions of the two etiologies, it is necessary to quantitively assess functional and mechanical deficits.

In this paper, a numerical Discrete Element Method (DEM) model was calibrated to investigate the transmission of force in granular media. To this aim, DEM simulation was performed for reproducing the behavior of a given granular material under uniform compression. The DEM model was validated by comparing the obtained shear stress/normal stress ratio with results published in the available literature. The network of contact forces was then computed, showing the arrangement of the material microstructure under applied loading...

Failure and pitting of teeth of gear affects transmission error. So, aim of this study was to define optimal tooth modifications introduced by performing static contact and deformation analysis, while trying to design spur gears to resist failure and pitting of the teeth. Behaviour of unusual contact between flywheel ring gear and starter motor pinion was analysed and optimized root fillet was introduced in spur gear.

There is no universal hip implant suitably fills all femoral types, whether prostheses of porous short-stem suitable for Hip Arthroplasty is to be measured scientifically. Mechanically, these four sorts of artificial joint replacement are stabilized in quantity. Cemented short-stem prostheses present the biggest stress, while porous short-stem & cemented long-stem designs are equivalently better than porous long-stem prostheses and alternatives for femoral-head replacement. The preferred design of those two depends on clinical conditions.

Knee movements performed in open (OKC) and closed (CKC) kinetic chains generate various patterns of muscle activities and especially distinct contact stresses in the patellofemoral joint (PFJ). In contrast to these features, the arthrokinematic motion quality (AMQ) of the PFJ has not been compared between mentioned conditions.

Plants are constantly exposed to stressful situations due to changing environmental conditions or through their contact with numerous pests and pathogenic microorganisms. Plants have evolved various strategies to defend themselves against these stresses. Plant responses to these stresses are complex and involve numerous physiological, molecular, and cellular adaptations.

The results of research revealed that 1) aspect of research management of faculty: proceding and experts‟ consideration encourage the faculty members more in doing research. However, there is still lack of research mentors and consultant in transfering research knowledge, advicing, and enhancing researchers‟ ability; 2) aspect of researcher: researchers have less amount of intention and commitment because of work load (teaching) which is not conducive to research and doing research is stressful and overtired.
