Elasticity Theory of a Twisted Stack of Plates [PDF]
, 1997 We present an elastic model of B-form DNA as a stack of thin, rigid plates or base pairs that are not permitted to deform. The symmetry of DNA and the constraint of plate rigidity limit the number of bulk elastic constants contributing to a macroscopic ...

Active Optics—Advances of Cycloid-like Variable Curvature Mirrors for the VLTI Array
Photonics, 2022 Elasticity theory and active optics led us to the discovery of three geometrical configurations of variable curvature mirrors (VCMs) that are either cycloid-like or tulip-like thickness distributions. Cycloid-like VCMs are generated by a uniform load—air

Stochastic Strike-Slip Fault as Earthquake Source Model
Mathematics, 2023 It is known that the source of a tectonic earthquake in the framework of the theory of elasticity and viscoelasticity is considered to be displacement along a certain fault surface.

Four simplified gradient elasticity models for the simulation of dispersive wave propagation [PDF]
, 2008 Gradient elasticity theories can be used to simulate dispersive wave propagation as it occurs in heterogeneous materials. Compared to the second-order partial differential equations of classical elasticity, in its most general format gradient elasticity ...

On plane Λ-fractional linear elasticity theory
Theoretical and Applied Mechanics Letters, 2020 : Non-local plane elasticity problems are discussed in the context of Λ-fractional linear elasticity theory. Adapting the Λ-fractional derivative along with the Λ-fractional space, where geometry and mechanics are valid in the conventional way, non-local

Wave Motion, 2011 The transformation theory of optics and acoustics is developed for the equations of linear anisotropic elasticity. The transformed equations correspond to non-unique material properties that can be varied for a given transformation by selection of the matrix relating displacements in the two descriptions.

An effective field theory of magneto-elasticity
SciPost Physics, 2022 We utilize the coset construction to derive the effective field theory of magnon-phonon interactions in (anti)-ferromagnetic and ferrimagnetic insulating materials.

Hyperelastic cloaking theory: Transformation elasticity with pre-stressed solids
, 2012 Transformation elasticity, by analogy with transformation acoustics and optics, converts material domains without altering wave properties, thereby enabling cloaking and related effects.

On the Microscopic Foundations of Elasticity
, 2002 The modeling of the elastic properties of disordered or nanoscale solids requires the foundations of the theory of elasticity to be revisited, as one explores scales at which this theory may no longer hold.
