Nonlinear elastic response of thermally damaged consolidated granular media [PDF]
, 2013 The mechanical properties of consolidated granular media are strongly affected by large temperature changes which induce the development and localization of stresses, leading in turn to damage, e.g., cracking.

DeepGreen: deep learning of Green’s functions for nonlinear boundary value problems
Scientific Reports, 2021 Boundary value problems (BVPs) play a central role in the mathematical analysis of constrained physical systems subjected to external forces. Consequently, BVPs frequently emerge in nearly every engineering discipline and span problem domains including ...

High contrast homogenisation in nonlinear elasticity under small loads [PDF]
, 2017 We study the homogenisation of geometrically nonlinear elastic composites with high contrast. The composites we analyse consist of a perforated matrix material, which we call the "stiff" material, and a "soft" material that fills the pores.

Nonlinear elasticity of stiff biopolymers connected by flexible linkers [PDF]
, 2009 Networks of the biopolymer actin, cross-linked by the compliant protein filamin, form soft gels. They can, however, withstand large shear stresses due to their pronounced nonlinear elastic behavior.

On fractional and fractal formulations of gradient linear and nonlinear elasticity [PDF]
Acta Mechanica, 2018 In this paper, we consider extensions of the gradient elasticity models proposed earlier by the second author to describe materials with fractional non-locality and fractality using the techniques developed recently by the first author.

Archive for Rational Mechanics and AnalysisAbstract Most theories and applications of elasticity rely on an energy function that depends on the strains from which the stresses can be derived. This is the traditional setting of Green elasticity, also known as hyper-elasticity. However, in its original form the theory of elasticity does not assume the existence of a strain energy ...

On nonlinear dilatational strain gradient elasticity
Continuum Mechanics and Thermodynamics, 2021 We call nonlinear dilatational strain gradient elasticity the theory in which the specific class of dilatational second gradient continua is considered: those whose deformation energy depends, in an objective way, on the gradient of placement and on the ...
