Accurate Inversion of High-Resolution Snow Penetrometer Signals for Microstructural and Micromechanical Properties [PDF]

open access: yes, 2009
Measurements of snow using a high-resolution micropenetrometer can be used to discriminate between different snow types; in lower-density snow the signal is sensitive to microstructure, and micromechanical properties can be estimated.

Multiscale Progressive Failure Analysis of 3D Woven Composites. [PDF]

open access: yesPolymers (Basel), 2022
Application of three-dimensional (3D) woven composites is growing as an alternative to the use of ply-based composite materials. However, the design, analysis, modeling, and optimization of these materials is more challenging due to their complex and ...

On the Thermomechanical Behavior of Laminated Composite Plates using different Micromechanical-based Models for Coefficients of Thermal Expansion (CTE) [PDF]

open access: yesJournal of Applied and Computational Mechanics
In this paper, the influence of the Coefficient of Thermal Expansion (CTE) on the thermal stress analysis of laminated composite plates is explored. By introducing the undetermined integral terms in the displacement field, a new simple and efficient ...

Effects of noise on the internal resonance of a nonlinear oscillator [PDF]

open access: yes, 2018
We numerically analyze the response to noise of a system formed by two coupled mechanical oscillators, one of them having Duffing and van der Pol nonlinearities, and being excited by a self-sustaining force proportional to its own velocity.

Micromechanics and dislocation theory in anisotropic elasticity [PDF]

open access: yesJournal of Micromechanics and Molecular Physics, 2016
In this work, dislocation master-equations valid for anisotropic materials are derived in terms of kernel functions using the framework of micromechanics. The second derivative of the anisotropic Green tensor is calculated in the sense of generalized functions and decomposed into a sum of a [Formula: see text]-term plus a Dirac [Formula: see text ...

Experimental and Theoretical Prediction Model Research on Concrete Elastic Modulus Influenced by Aggregate Gradation and Porosity

open access: yesSustainability, 2021
In this research, we developed a four-phase model, which takes the aggregate gradation and porosity into account in the prediction of the elastic modulus of concrete, based on the micromechanical theories.

Mechanism-based strain gradient plasticity— I. Theory

open access: yes, 1999
A mechanism-based theory of strain gradient plasticity (MSG) is proposed based on a multiscale framework linking the microscale notion of statistically stored and geometrically necessary dislocations to the mesoscale notion of plastic strain and strain ...

Investigation of CNT Defects on Mechanical Behavior of Cross linked Epoxy based Nanocomposites by Molecular Dynamics [PDF]

open access: yesInternational Journal of Advanced Design and Manufacturing Technology, 2016
Although carbon nanotubes (CNT) have been employed as reinforcements in nanocomposites, presence of nano scale defects such as Stone-Wales and vacancy defects in carbon nanotubes (CNT) weakens the mechanical properties of these materials.
