...Xiaojie Ma; Luqi Liu; Zhong Zhang; Yueguang Wei We study the bending stiffness of symmetrically bent circular multilayer van der Waals (vdW) material sheets, which correspond to the nonisometric configuration in bulge tests. Frenkel sinusoidal function is employed to describe the periodic...

...Xiaojie Ma; Luqi Liu; Zhong Zhang; Yueguang Wei We consider how the bending stiffness of a multilayer graphene sheet relies on its bending geometry, including the in-plane length L and the curvature κ. We use an interlayer shear model to characterize the periodic interlayer tractions due...

...Shizhen Yin; Yewang Su Laminated ribbons have been widely adopted for structures of flexible electronics to simultaneously achieve the electronic functions and mechanical performances. Their effective tensile stiffness and bending stiffness, which are extensively used as fundamental parameters...

... 2013 In this paper we attempt to answer two questions on graphene from a mechanic's viewpoint: why does this one-atom-thick monolayer have finite bending stiffness to ensure its stability? and what is its wrinkle mechanism? As for the first question, it is found that the repulsive residual...

... are compared with an equivalent honeycomb model. The study showed the effect of work hardening is very important to assess bending stiffness of truss core panel. It is also observed that the use of suitable shell formulation is necessary to obtain reliable result. In addition, the truss core panel shows...

...Bart Raeymaekers; Frank E. Talke The lateral motion of a tape moving axially over a cylindrical guide surface is investigated. The effects of lateral bending stiffness and friction force are studied and the attenuation of lateral tape motion as a function of the guide radius and friction...
