The static pull-in instability of beam-type micro-electromechanical systems is theoretically investigated. Two engineering cases including cantilever and double cantilever micro-beam are considered. Considering the mid-plane stretching as the source of the nonlinearity in the beam behavior, a nonlinear size-dependent Euler-Bernoulli beam model is used based on a modified couple stress theory, c...

The behavior and structure of Rb are explored up to 264 GPa, a pressure at which the density is increased more than eightfold. previously predicted double-hexagonal close packed stable above 200 while lower pressures change in compressibility 30 GPa arises from $s$-$d$ charge transfer. Above authors find that has regular compression $d$-type transition metal.

This paper discusses the static and fatigue behavior of adhesively bonded single lap joints in SMC-SMC composites. Effects of lap length and adhesive thickness on the static and fatigue strength of SMC-SMC adhesive joints are studied. Effects of SMC surface preparation and test speed on the joint performance are evaluated. Finally, the effect of water exposure on the joint durability is also in...
