Well-Posedness Analysis for a Linearization of a Fluid-Elasticity Interaction
SIAM Journal on Mathematical Analysis, 2015Summary: We study the well-posedness of a total linearization, with respect to a perturbation of the external forcing, of a free-boundary nonlinear elasticity-incompressible fluid interaction. The total linearization for the coupling modeled by the Navier-Stokes equations and the nonlinear equations of elastodynamics was obtained recently in [the first

Analysis of an HDG method for linear elasticity
International Journal for Numerical Methods in Engineering, 2014SummaryWe present the first a priori error analysis for the first hybridizable discontinuous Galerkin method for linear elasticity proposed in Internat. J. Numer. Methods Engrg. 80 (2009), no. 8, 1058–1092. We consider meshes made of polyhedral, shape‐regular elements of arbitrary shape and show that, whenever piecewise‐polynomial approximations of ...

General Analysis of Linear Nematic Elasticity
Journal of Engineering Physics and Thermophysics, 2004The results of a general analysis of linear nematic elasticity on the basis of the five-parameter thermodynamic potential of de Gennes (DG) have been presented. It has been shown that, depending on the similarity of the material parameters to the conditions of marginal (limiting) stability, the DG potential describes the entire diversity of soft ...

Residue analysis in linearized elastic inversion
SEG Technical Program Expanded Abstracts 1995, 1995Amplitude-versus-Offset (AVA) information is used for estimation of the elastic parameters. We introduce a method based on the linearized Zoeppritz equation to separate the linear AVA behavior from the nonlinear and noise terms, which we call the residue.

Piecewise linear elastic–plastic analysis
International Journal for Numerical Methods in Engineering, 1979AbstractThe purpose of this paper is to show that a mathematical programming method, due to Maier and his co‐workers, of nonlinear structural analysis can be rerformulated so that greater computational efficiences are achived. The methods are designed for a class of elastic–plastic structures under ‘piecewise linear’ assumptions and solve among others ...

Linearized analysis of Richtmyer–Meshkov flow for elastic materials
Journal of Fluid Mechanics, 2005We present a study of Richtmyer–Meshkov flow for elastic materials. This flow, in which a material interface is struck by a shock wave, was originally investigated for gases, where growth of perturbations of the interface is observed. Here we consider two elastic materials in frictionless contact.

Analysis of Linear Elastic Masonry-Like Solids Subjected to Settlements
Key Engineering Materials, 2022A linear elastic no-tension material model is implemented in this contribution to cope with the analysis of masonry-like solids in case of either elastic or inelastic settlements. Instead of implementing an incremental non-linear approach, an energy-based method is adopted to address the elastic no-tension equilibrium.

Linear Buckling Analysis of Structures on the Elastic Support
2022In this paper, a numerical model for the linear buckling analysis of structures on the elastic support is presented. In the proposed numerical model, the structural elements are modeled with the Euler beam finite element with linearized kinematics and von Karman deformation measure, whereas the elastic support is modeled with the elastic rotational ...
