A two-stage calibration method for industrial robots with joint and drive flexibilities [PDF]

open access: yesMechanical Sciences, 2015
Dealing with robot calibration the neglection of joint and drive flexibilities limit the achievable positioning accuracy significantly. This problem is addressed in this paper.

Coordinated Optimization Model of Active Power and Reactive Power in Power and Gas Systems with the Objective of Carbon Neutrality

open access: yesShanghai Jiaotong Daxue xuebao, 2021
With the objective of carbon neutrality, renewable energy resources gradually become the main power supply, whose variability poses great challenges to the operation and optimization of the system, especially to the power distribution network.

Constitutive equations and wave propagation in Green\u2013Naghdi type II and III thermoelectroelasticity [PDF]

open access: yes, 2016
In this article we extend the theory of thermoelasticity devised by Green and Naghdi to the framework of finite thermoelectroelasticity. Both isotropic and transversely isotropic bodies are considered and thermodynamic restrictions on their constitutive ...

Buckling of a composite bar made of a functional-gradient material with an inhomogeneous pre-stress field

open access: yesMATEC Web of Conferences, 2018
Within the 3D nonlinear elasticity we discuss the linear instability of a composite bar made of a functially graded material and having initial stresses. The bar consists of two layers which are inflated for a annular wedge of a circular cylinder.

Stability of a composite thick plate with an inhomogeneous field of initial stresses

open access: yesMATEC Web of Conferences, 2018
We discuss the linear stability analysis for a rectangular twolayered elastic plate. Each layer of the plate was obtained due to inflation of an annular wedge of a cylinder. As a result, in the plate there are initial stresses.

Generalized Korn's inequality and conformal Killing vectors

open access: yes, 2005
Korn's inequality plays an important role in linear elasticity theory. This inequality bounds the norm of the derivatives of the displacement vector by the norm of the linearized strain tensor.

Investigation of buckling modes of sandwich specimens with facing layers from [0°]s fiber-reinforced plastic under axial compression

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки, 2019
Analytical solutions to the linearized problems on possible macroscale buckling modes of sandwich specimens made from fiber-reinforced plastics with lay-up sequence [0°]s ( s is the number of laminas) under axial compression were analyzed.

Asymptotic models for curved rods derived from nonlinear elasticity by Gamma-convergence

open access: yes, 2008
We study the problem of the rigorous derivation of one-dimensional models for a thin curved beam starting from three-dimensional nonlinear elasticity. We describe the limiting models obtained for different scalings of the energy.

One-dimensional von K\'arm\'an models for elastic ribbons [PDF]

open access: yes, 2017
By means of a variational approach we rigorously deduce three one-dimensional models for elastic ribbons from the theory of von K\'arm\'an plates, passing to the limit as the width of the plate goes to zero.

Traveling waves in one-dimensional nonlinear models of strain-limiting viscoelasticity [PDF]

open access: yes, 2015
In this article we investigate traveling wave solutions of a nonlinear differential equation describing the behaviour of one-dimensional viscoelastic medium with implicit constitutive relations.
