Symmetry considerations for topology design in the elastic inverse homogenization problem
(Pergamon-Elsevier Science Ltd, 2019-07)
An analysis of the symmetries characterizing the micro-architecture topologies and the elastic material properties is performed. The goal is to elucidate a systematic procedure that facilitates the design of elastic ...
Making use of Symmetries in the 3D Elastic Inverse Homogenization Problem
(Begell House, 2019-03)
An analysis of the connection between the symmetry of the material layout at the microscale and the properties of the effective elasticity of 3D periodic composites is performed. We analyze some possible Bravais lattices ...
Transverse free vibration of non uniform rotating Timoshenko beams with elastically clamped boundary conditions
(Springer, 2013-08)
In the present paper the Differential Quadrature Method, DQM, and the domain decomposition are used to carry out the free transverse vibration analysis of non-uniform multi-span rotating Timoshenko beams with perfect and ...
Free vibrations of Bernoulli-Euler beams with intermediate elastic support: A concise thematic recension
(Academic Press Ltd - Elsevier Science Ltd, 2005-03)
The problem of a beam elastically restrained at intermediate points is often encountered in the design of structural members of buildings, aircrafts, ships, pipes, robotic applications and an extensive variety of other ...
Strain distribution due to surface domains: A self-consistent approach with respect to surface elasticity
(Beilstein-Institut Zur Forderung der Chemischen Wissenschaften, 2015-01)
Elastically mediated interactions between surface domains are classically described in terms of point forces. Such point forces lead to local strain divergences that are usually avoided by introducing a poorly defined ...
Variational Approach of Timoshenko Beams with Internal Elastic Restraints
(David Publishing Company, 2013-10)
An exact approach for free transverse vibrations of a Timoshenko beam with ends elastically restrained against rotation and translation and arbitrarily located internal restraints is presented. The calculus of variations ...
Topological sensitivity analysis in heterogeneous anisotropic elasticity problem. Theoretical and computational aspects
(Elsevier Science Sa, 2016-11)
The topological sensitivity analysis for the heterogeneous and anisotropic elasticity problem in two-dimensions is performed in this work. The main result of the paper is an analytical closed-form of the topological ...
Mimetization of the elastic properties of cancellous bone via a parameterized cellular material
(Springer Heidelberg, 2017-10-03)
Bone tissue mechanical properties and trabecular microarchitecture are the main factors that determine the biomechanical properties of cancellous bone. Artificial cancellous microstructures, typically described by a reduced ...
Numerical technique for the 3D microarchitecture design of elastic composites inspired by crystal symmetries
(Elsevier Science SA, 2020-02)
A numerical methodology developed for the microarchitecture design of 3D elastic two-phase periodic composites with effective isotropic properties close to the theoretical bounds is here presented and analyzed. This ...
Inversion of Elastic Light Scattering Measurements to Determine Refractive Index and Particle Size Distribution of Polymeric Emulsions
(Taylor & Francis Ltd, 2003-08-01)
Polymeric emulsions are well characterized by the knowledge of their particle size distributions (PSD). Elasticlight-scattering (ELS) measurements can be inverted to estimate the PSD in the range from 50 nm up to several ...
