The surface characteristics of the contact zone of tin-plated copper alloy contacts subjected to fretting motion for 8000, 16,800 and 48,000 cycles under unlubricated conditions are presented. The nature of the contact zone, at the verge of wearing out of the tin coating as well as upon the coating is completely worn out, is assessed using scanning electron microscopy (SEM), energy-dispersive X...

for finding the optimal choices of applied remote loads – normal force, moment, shear force and bulk stresses needed to solve frictional contact problems in partial-slip using half-plane theory are derived by data from contacts analysed finite element method. While forces moment readily found equilibrium considerations, order determine we must exploit details traction ratio direct strain within...

A contact/friction isoparametric finite element for the analysis of connections between laminated composite plates is presented. The element is compatible with a three-dimensional plate element based on layer-wise constant shear theory. The contact/friction element is based on a simple regularization of the unilateral contact with an orthotropic Coulomb friction problem. Two different friction ...

Abstract A precise modeling of the capacitance rolling element bearings is increasing significance over last years, e.g. in context bearing damage estimation electric drives. The complexity a steel as an electrical network makes reliable validation calculation models under realistic operating conditions nearly impossible. way to reduce yet use hybrid with single element. This helps measure only...

Three physiologically characterized spindle (group Ia) afferents were labeled by the intracellular injection of HRP and were processed for light-level reconstruction. Thirty-five boutons in the ventral horn were then selected for analysis. They were serially thin sectioned and characterized in terms of volume, total surface area and the surface area of apposition to postsynaptic neurons (appose...
