Non-Hookean large elastic deformation in bulk crystalline metals [PDF]
Nature Communications, 2022 Engineering metals often suffer from a small elastic deformation with a linear stress-strain relationship obeying Hooke’s law. Here the authors observe a large nonlinear tensile elastic deformation with a strain of >4.3% in a bulk Cu alloy that offers ...

Elastic Deformation of Polycrystals [PDF]
Physical Review Letters, 2002 We propose a framework to model elastic properties of polycrystals by coupling crystal orientational degrees of freedom with elastic strains. Our model encodes crystal symmetries and takes into account explicitly the strain compatibility induced long ...

Elastic deformation of twinned microstructures. [PDF]
Proc Math Phys Eng Sci, 2017 Many crystalline materials exhibit twinned microstructures, where well-defined orientation relationships define the special symmetry between different, elastically anisotropic twin variants. When such twins are subjected to external loading, additional internal stresses necessarily occur at the twin boundaries in order to maintain compatibility.

Elastically deformable models [PDF]
Proceedings of the 14th annual conference on Computer graphics and interactive techniques, 1987 The theory of elasticity describes deformable materials such as rubber, cloth, paper, and flexible metals. We employ elasticity theory to construct differential equations that model the behavior of non-rigid curves, surfaces, and solids as a function of time.

The activation energy of viscoelastic deformation of rocks [PDF]
Geološki Anali Balkanskoga Poluostrva, 2003 The suggested model, which considers the simultaneous appearance (on the intermolecular scale) of elastic and viscous behaviors of rocks during their viscoelastic deformation, enables the relaxation time, t0, of the viscoelastic deformation energy to be ...

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2021 In cylindrical traverse grinding, a slender workpiece is bent by the normal grinding force due to its low stiffness. Consequently, a form error is generated by the elastic deformation of the workpiece during the grinding process.
