Explicit parametric solutions of lattice structures with proper generalized decomposition (PGD): applications to the design of 3D-printed architectured materials [PDF]

, 2018
The final publication is available at Springer via http://dx.doi.org/10.1007/s00466-017-1534-9Architectured materials (or metamaterials) are constituted by a unit-cell with a complex structural design repeated periodically forming a bulk material with ...

Negative Stiffness Induced and Controlled by Constriction

physica status solidi (b), EarlyView.
Structures with negative stiffness can be stabilized by constriction of external displacement. Furthermore, constriction can make a conventional positive stiffness material exhibit negative stiffness, either bidirectional or unidirectional (shown in the figure).

An orthotropic non-local approach to modeling intra-laminar damage progression in laminated composites

, 2019
A non-local macroscopic constitutive model is presented to simulate the progression of intra-laminar damage in laminated composite structures. A novel feature of the model is an orthotropic, non-local averaging scheme that is specially designed to ...

Analysis of orthotropic tensegrity plate strips using a continuum two-dimensional model [PDF]

MATEC Web of Conferences, 2019
A continuum two-dimensional model of orthotropic moderately thick plate strip is proposed in this paper. The model considers the different reference planes (lower, middle and upper) thus the different planes of support may be taken into account.

Numerically efficient mechanical modeling of reinforced concrete membrane elements with fixed, interlocked cracks

Structural Concrete, EarlyView.
Abstract Compression field approaches such as the Cracked Membrane Model with fixed, interlocked cracks (CMM‐F) are efficient tools for the mechanical modeling of reinforced concrete elements, providing the mechanical model σ=fε$$ \boldsymbol{\upsigma} =f\left(\boldsymbol{\upvarepsilon} \right) $$ required for finite element analyses.

About instability in an elastic Cosserat body with pores

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
This article is centered on the study of the isotropic, porous Cosserat elastic media, realized by means of a parallel with the media of the same type, but anisotropic, by following the rewriting in a new form of the equations that govern this theory ...

Simple and detailed modeling of corrosion‐affected slender shear critical RC beams

Structural Concrete, EarlyView.
Abstract The corrosion of steel bars compromises both the safety and the serviceability of reinforced concrete (RC) structures. Consequently, reliable tools are required to estimate the detrimental effects of corrosion on the structural response of RC members subjected to transverse loads.

Dynamic response to plane strain problem of multilayered orthotropic foundation under moving loads

Yantu gongcheng xuebao, 2018
Based on the dynamic equation for plane strain problem of single-layer orthotropic foundation under moving harmonic loads, the transfer matrix of single-layer orthotropic foundation in the Cartesian coordinates is deduced through the Fourier transform ...

Modelling the radiation efficiency of orthotropic cross-laminated timber plates with simply-supported boundaries

Applied Acoustics, 2019
In this paper two prediction models to evaluate the radiation efficiency of orthotropic plates, developed with different approaches, are presented. A sound radiation model, based on an analytical/modal approach, is developed for a thin orthotropic plate,
