The interaction of acoustic waves with fluid-loaded shell structures is an ongoing area of interest in underwater acoustics, ship construction and detection. The elasticity of the structure permits strong surfaceborne wave effects, which can be significant or dominant in large structures (many wavelengths in size). The significance of surface borne waves is compounded by low loss factors, enabl...

The development of theoretical models and experimental methods of cell mechanics are actual task. On the bases of the shell theory we consider the elastic properties of the cells and compeer them with the experimental resuts which was received using atomic force microscopy (AFM) date. The experimental calculations were made on the bases of the Herz model. It was shown that the shell theory allo...

Apical constriction is one of the fundamental mechanisms by which embryonic tissue is deformed, giving rise to the shape and form of the fully-developed organism. The mechanism involves a contraction of fibres embedded in the apical side of epithelial tissues, leading to an invagination or folding of the cell sheet. In this article the phenomenon is modelled mechanically by describing the epith...

We derive, from an empirical interaction potential, an analytic formula for the elastic bending modulus of single-layer MoS2 (SLMoS2). By using this approach, we do not need to define or estimate a thickness value for SLMoS2, which is important due to the substantial controversy in defining this value for two-dimensional or ultrathin nanostructures such as graphene and nanotubes. The obtained e...

Cardboard liners are often installed within automotive drive shafts to reduce radiated noise over a certain frequency range. However, the precise mechanisms that yield noise attenuation are not well understood. To overcome this void, a thin shell (under free boundaries) with different cardboard liner thicknesses is examined using analytical, computational and experimental methods. First, an exp...

The work described in this paper is concerned with providing a rational asymptotic analysis for the partial wrinkling bifurcation of thin elastic hemispherical segment which upper rim experiences in-plane circular shearing relative to other edge. mathematical structure associated complex-valued boundary eigenvalue problem revealed by using method matched expansions. Our key result three-term fo...
