Thermal buckling behavior of truncated conical liner reinforced by laminated composite is investigated in the presence of a general initial imperfection. For this purpose, the method of virtual work and first-order strain-deformation shell theory are employed to extract equilibrium equations. To this end, a finite element code is developed using the 3D 8-node shell element with six degrees of f...

During milking the teat cup liner is the interface between the teat of a dairy cow and the milking system, so it should be very well adapted to the teat. Therefore, the aim of the present study was to determine the effect of liner type on the directly measuring teat load caused by a collapsing liner with a pressure-indicating film. The Extreme Low pressure-indicating film was used to detect the...

Core@shell and concentration-gradient particles have attracted much attention as improved cathodes for Li-ion batteries (LIBs). However, most of their preparation routes have employed a precisely-controlled co-precipitation method. Here, we report a facile preparation route of core@shell and concentration-gradient spinel particles by dry powder processing. The core@shell particles composed of t...

The probability of brain injury during an accident is dependent on the force history acting on brain tissue. The mostly used criterion for the injury probability assessment, the Head Injury Criterion (HIC), is based on the time integral of force (acceleration) history curve. HIC is used in the work for the assessment of helmet performance. Because of limited weight of the helmet, current design...

Polyethylene wear of acetabular components is a key factor in the development of periprosthetic osteolysis and wear at the articular surface has been well documented and quantified, but fewer data are available about changes which occur at the backside of the liner. At revision surgery for loosening of the femoral component we retrieved 35 conventional modular acetabular liners of the same desi...

Abstract In order to further improve the flight stability of explosively formed projectile, formation method tail EFP was studied based on polygonal liner. Under hexagonal charge structure, fins can be when structural parameters are matched. Through numerical simulation LS-DYNA, influence liner (curvature radius, linear thickness), height and shell thickness velocity, length-diameter ratio, com...
