Classification of Jacobi solutions of double dispersion equation in uniform and inhomogeneous Murnaghan’s rod

Partial Differential Equations in Applied Mathematics
The double dispersion equation comprising the Lame coefficient, nonlinear coefficient, and Poisson ratio components is described as the uniform and inhomogeneous Murnaghan’s rod by A. M. Samsonov in Samsonov (2001). In this work, we apply the F expansion

Trefftz functions using the fundamental solution with the singularity outside the domain

Computer Assisted Methods in Engineering and Science, 2023
Two types of Trefftz (T -) functions are often used - fundamental solutions with their singularities outside the given region and general solutions of homogenous differential equations.

Nonlinear amplitude-variation-with-offset inversion for Lamé parameters using a direct inversion method

, 2017
Prestack seismic inversion is widely used in fluid indication and reservoir prediction. Compared with linear inversion, nonlinear inversion is more precise and can be applied to high-contrast situations.

First Basic Problem of Elasticity Theory for a Composite Layer with Two Thick-Walled Tubes

Journal of Mechanical Engineering
The spatial problem of elasticity theory for a fibrous composite in the form of a layer with two thick-walled cylindrical tubes is solved. Stresses are given on the flat surfaces of the layer and on the inner surface of the tubes.

Boundary Value Problems of Mechanics for Shape Memory Alloys [PDF]

Учёные записки Казанского университета: Серия Физико-математические науки, 2015
The variants of constitutive equation systems for shape memory alloys (SMAs) are considered. Different statements of boundary value problems of deformable solids mechanics for these materials (non-coupled, coupled, and twice-coupled problems; stability ...

Correlation analysis between coiling tension and the sleeve's hoop stress

Mechanics & Industry
The coiling process, crucial for winding long sheets of consistent thickness, often encounters challenges due to deformation induced by pressure and frictional forces on the inner mandrel and sleeve.

ROOT ASYMPTOTICS OF SPECTRAL POLYNOMIALS FOR THE LAMÉ OPERATOR

, 2008
. The study of polynomial solutions to the classical Lamé equation in its algebraic form, or equivalently, of double-periodic solutions of its Weierstrass form has a long history.

Algebraic Solutions of the Lamé Equation, Revisited

, 2002
A minor error in the necessary conditions for the algebraic form of the Lamé equation to have a finite projective monodromy group, and hence for it to have only algebraic solutions, is pointed out. [See F.
