WebThe central problem in a solid mechanics problem is generally to determine the displacement field , Cauchy stress distribution (or some other stress measure) and (sometimes) temperature , as functions of position (usually … WebIn literatures, this phenomenon is referred to as the “surface-energy” effect and induces the size dependency of nano-sized structures. To enhance structural-mechanics models with the surface-energy effect, the surface elasticity theory of Gurtin and Murdoch [46,47] has been widely adopted [48–54]. In this surface elasticity model, the ...
