The present problem deals with the propagation of Love-type surface waves in a bedded structure comprises of an inhomogeneous orthotropic layer and an elastic half-space. The upper boundary and the interface between two media are considered to be corrugated. An analytical method (separation of variables) is adapted to solve the second order PDEs, which governs the equations of motion. Equations...

The paper studies the possibility of propagation of torsional surface waves in an elastic layer with void pores over an elastic medium with void pores using the mechanics of the medium as derived by Cowin and Nunziato. The velocity equation has been derived and the results have been discussed. The study reveals that there may be more than one torsional surface wave fronts and one Love wave fron...

The theory of load-induced relaxation of the layered Maxwell half-space is applied to the study of glacioisostatic adjustment in Fennoscandia. The interpretation uses emergence data from Angermanland (Sweden) and uplift-rate data from the Gulf of Bothnia. With mantle viscosity fixed at 10 Pa s, the data can be explained by an earth model characterized by (a) an elastic surface layer of conventi...

Mode selection of guided waves in an elastic steel plate with thick coating layer has been studied here. E€ect of both thick elastic coating and damping of the coating layer on the dispersion and mode shapes has been investigated and modes that are less a€ected by elastic coating and damping have been identi®ed. For modeling the viscoelastic behavior of the coating layer, the standard linear so...

This paper develops a model for evolving wrinkles in a bilayer thin film consisting of an elastic layer and a viscoelastic layer. The elastic layer is subjected to a compressive residual stress and is modeled by the nonlinear von Karman plate theory. A thin-layer approximation is developed for the viscoelastic layer. The stability of the bilayer and the evolution of wrinkles are studied first b...

In large-angle elastic scattering events of keV electrons a significant amount of momentum is transferred from the electron to a nucleus in the target. As a consequence kinetic energy is transferred from the energetic electron to the nucleus, and hence these processes can be referred to as ‘quasi-elastic’. How much energy is transferred depends on the mass of the nucleus. In this paper, we pres...

Thoracic aorta were elastic type, tunica intima consisted of a single layer of flattened endothelial cells, sub endothelial layer and indistinct internal elastic membrane. Tunica media is thickest among the three layers and welldefined elastic lamellae, they were separated by circularly arranged smooth muscle, collagen fibers and reticular fibers. External elastic membrane was not distinguishab...

Although the viscoelasticity or tackiness of a pressure-sensitive adhesive gives it strength owing to energy dissipation during peeling, it also renders it nonreusable because of structural changes such as the formation of fibrils, cohesive failure, and fouling. However, an elastic layer has good structural integrity and cohesive strength but low adhesive energy. We demonstrate an effective com...
