In this study, CTEs of a high performance 3D orthogonal woven C/C composite at high temperature are studied by multi-scale mechanical modeling using the finite element method.
To address this problem, this study proposes a multi-scale mechanical model using a triphasic formulation (solid, fluid, unbound matrix molecules) based on a single chondrocyte releasing extracellular matrix molecules within a degrading hydrogel.
Secondly, we have developed a mechanical model using finite elements analysis (FEA) calculation method: this one permits to obtain the optimal mechanical design of the device in order to achieve a 200 nm tuning range with a bias voltage of around 15 V (usual value for this kind of device).
MRI is used to measure strain and a finite element mechanical model using pressure measurements is used to estimate myofiber stress.

Although the mechanical model used in this paper is an ideal one, the dynamic responses of the human body in vehicle traveling on rough terrain is useful for the rough evaluation of the human body safety in traveling vehicles.
The mechanical model used here is based on a combination of classical elastodynamic theory for the bulk solid under non-classical boundary conditions, supplemented with a localized constitutive equation for the solid-inclusion interface in the framework of the Gurtin Murdoch theory of surface elasticity.
The non-linear mechanical model used for the estimation of the crack load and the deflection profile of the beam in post-cracking phase is able to catch the experimental measurements and provides further confirmation of the validity of the formulation adopted for the estimation of pre-stressing losses over time and the subsequent deflection profile.
In this work, a three-dimensional fully coupled hydro-mechanical model using material point method (MPM) is developed.
Micro-mechanical modeling using finite element analysis confirms that localization of plastic flow should occur between elongated 'hole shaped voids', despite their rather small initial cross-section size (2.5 μm) and comparatively large spacing (70 μm).
Quantum mechanical models, typically using density functional theory (DFT), have been used to examine the base pairing and stacking of both unmodified (wild-type) and 5-mC DNA.
