Learning hidden elasticity with deep neural networks [PDF]
, 2020 We introduce a de novo elastography method to learn the elasticity of solids from measured strains. The deep neural network in our new method is supervised by the theory of elasticity and does not require labeled data for training. Results show that the proposed method can learn the hidden elasticity of solids accurately and is robust when it comes to ...

Spline-Interpolation Solution of Elasticity Theory Problems [PDF]
Учёные записки Казанского университета: Серия Физико-математические науки, 2015 A spline-interpolation solution of static and dynamic elasticity theory problems is suggested. The method allows to solve the problems for solids with plane sections parallel to the plane XOY.

Nonlinear elasticity of composite networks of stiff biopolymers with flexible linkers [PDF]
Phys. Rev. Lett. 101, 118103 (2008), 2007 Motivated by recent experiments showing nonlinear elasticity of in vitro networks of the biopolymer actin cross-linked with filamin, we present an effective medium theory of flexibly cross-linked stiff polymer networks. We model such networks by randomly oriented elastic rods connected by flexible connectors to a surrounding elastic continuum, which ...

A higher order control volume based finite element method to prodict the deformation of heterogeneous materials [PDF]
, 2013 Materials with obvious internal structure can exhibit behaviour, under loading, that cannot be described by classical elasticity. It is therefore important to develop computational tools incorporating appropriate constitutive theories that can capture ...

A midsurface elasticity model for a thin, nonlinear, gradient elastic plate [PDF]
arXiv, 2023 In this paper, we derive a dynamic surface elasticity model for the two-dimensional midsurface of a thin, three-dimensional, homogeneous, isotropic, nonlinear gradient elastic plate of thickness $h$. The resulting model is parameterized by five, conceivably measurable, physical properties of the plate, and the stored surface energy reduces to Koiter's ...

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.

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 ...

Interaction of punches on orthotropic half-space
Advanced Engineering Research, 2016 An integral equation of the three-dimensional contact problem for an orthotropic half-space (9 independent elastic parameters in Hooke’s law) is obtained where its kernel does not include integrals, but it depends on the solution of a characteristic ...
