A layer of homogeneous, isotropic, elastic material overlays a substrate of similar material. The shear wavespeed within the layer is less than that of the substrate causing waves to be trapped within ...

Two-dimensional materials, such as graphene and MoS 2, are films of a few atomic layers in thickness with strong in-plane bonds and weak interactions between the layers. The in-plane elasticity has ...

Figure 1: Crystal structure of hexagonal RMnO 3 with arrows indicating experimentally observed atomic displacements. Figure 3: Temperature dependence of the Mn x position and the Mn–O bond distances ...

Why a flexible coupling? A flexible coupling exists to transmit power (torque) from one shaft to another; to compensate for minor amounts of misalignment; and, in certain cases, to provide protective ...
