Bimaterial microcantilevers are used in numerous applications in microelectromechanical systems (MEMS) for thermal, mechanical, optical, tribological and biological functionalities. Unfortunately, the residual stress-induced curvature and combined effects of creep and stress relaxation in the thin film significantly compromises the performance of these structures. To fully understand the themom...

Elastic stability criteria, derived for a homogenous lattice under arbitrary external load, provide an upper bound on the critical stress or strain which a crystalline solid can withstand. Since the onset of a structural instability is load dependent, the corresponding theoretical strength can be given similar interpretation. When combined with molecular dynamics simulation, such results allow ...

Considering importance of stress concentration around holes and notches of arbitrary shape in a given elastic medium for modern engineering, a two dimensional model for a thermoelastic problem in an hexagon region with an elliptic hole is established. The expressions for the temperature distribution and thermal stresses which have their importance in nuclear engineering are obtained for the mod...

The problem treated here is to determinethe viscosity effect on stresses, temperature change and chemical potential in a circular plate.
