Vibration analysis of nonlinear and linear elastic systems
Вестник Дагестанского государственного технического университета: Технические науки, 2021 Objective. In this study, the task is to establish the theoretical prerequisites for the operability of a regressive-progressive elastic mechanism by comparing the amplitude-frequency characteristics and phase trajectories with a linear elastic system of

Slope stability analysis: Barodesy vs linear elastic – perfectly plastic models [PDF]
E3S Web of Conferences, 2019 The results of slope stability analysis are not unique. Different factors of safety are obtained investigating the same slope. The differences result from different constitutive models including different failure surfaces. In this contribution, different

Crack paths and the linear elastic analysis of cracked bodies [PDF]
Fracture and Structural Integrity, 2015 The linear elastic analysis of cracked bodies is a Twentieth Century development, with the first papers appearing in 1907, but it was not until the introduction of the stress intensity factor concept in 1957 that widespread application to practical ...

A Quadratic Elasticity Formulation for Dynamic Interacting Structures in Flow [PDF]
MATEC Web of Conferences, 2021 The deformation of slender elastic structures due to the motion of surrounding fluid is a common multiphysics problem encountered in many applications. In this work we detail the development of a numerical model capable of solving such strongly-coupled ...

Revisiting the wrinkling of elastic bilayers I: linear analysis [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2019 Wrinkling is a universal instability occurring in a wide variety of engineering and biological materials. It has been studied extensively for many different systems but a full description is still lacking. Here, we provide a systematic analysis of the wrinkling of a thin hyperelastic film over a substrate in plane strain using stream functions.

Asymptotic Analysis of Ambrosio--Tortorelli Energies in Linearized Elasticity [PDF]
SIAM Journal on Mathematical Analysis, 2014 We provide an approximation result in the sense of $\Gamma$-convergence for energies of the form $\int_\Omega\mathscr{Q}_1(e(u))\,dx+a\,\mathcal{H}^{n-1}(J_u)+b\,\int_{J_u}\mathscr{Q}_0^{1/2}([u]\odot\nu_u)\,d\mathcal{H}^{n-1}$, where $\Omega\subset\mathbb{R}^n$ is a bounded open set with Lipschitz boundary, $\mathscr{Q}_0$ and $\mathscr{Q}_1$ are ...
