The control of thermal cracks induced by the effect early age are main concerns in concrete dam during construction stage. Despite its importance, detailed analysis gravity dams period is relatively rarely literature, eventually because prediction behavior on stage requires taking into account several phenomena and interaction, demands a considerable computational effort. To overcome this drawb...

An approximate method is presented to investigate Mgy the interlaminar stresses near the free edges of composite N laminate plates that are subjected to a combined NI~ thermo-mechanical loading. The method is based upon N~ admissible function representations of stresses which account Q!~) for the effects of both the global mismatches and the local ,~!k/ mismatches in two of the elastic properti...

This paper presents a finite element numerical method to assess the stress state and gradients induced by thermo-oxidative ageing in Ti/epoxy/Ti adhesively bonded joints for aircraft engine applications. The is dealing with couplings between thermal, chemistry mechanics occurring during high-temperature of joint, taking into account post-curing stresses, under mechanical loading. Calculations a...

Future gravitational-wave detectors operated at cryogenic temperatures are expected to be limited by thermal noise of the highly reflective mirror coatings. Silicon nitride is an interesting material for such coatings as it shows very low mechanical loss, a property related to low thermal noise, which is known to further decrease under stress. Low optical absorption is also required to maintain...

Generation and dissipation of temperature-induced pore water pressure can alter the mechanical behavior characteristics soil media. Experimental observations indicate that heating/cooling cycles fabric which may result in irrecoverable deformations. Previous studies suggest contribution thermo-osmotic (non-Darcian) flow clays have a significant role thermal pressurization diffusion. Hence, this...

This paper presents a coupled thermal-hydraulic-mechanical (THM) model for simulating failure processes in geological media. The coupling between stress/strain and heat transfer describing how thermal expansion affects stress is based on the theory of thermo-elasticity. Additionally, fluid flow pore-pressure governed by Biot's consolidation theory. Stress/strain-dependent porosity/permeability/...

The objective of this study was to manufacture new biodegradable fiberboards by thermo-pressing. The starting material was deoiled cake (only 0.9% oil content), generated during the biorefinery of sunflower (Helianthus annuus L.) whole plant in a co-rotating twin-screw extruder. All fiberboards were cohesive mixtures of proteins and lignocellulosic fibers, acting respectively as binder and rein...

We present in this supplement to our manuscript entitled, “Static and Dynamic Wavelength Routing via the Gradient Optical Force,” the detailed analysis related to the cavity response in the pump-probe scheme, the anti-crossing of cavity modes, and the calibration of thermo-optic and thermo-mechanical contributions to the cavity resonance tuning.

giant unilamellar vesicles (guvs) consisting in self-closed lipid bilayers of 0.5-100 µm diameter are considered as oversimplified models of cells because of their biological membrane and micrometric size while large unilamellar vesicles (luvs) of 100-500 nm diameter have applications in drug delivery. to improve structural and mechanical properties of these vesicles, we have developed two cate...

In this paper, we examine the coupled thermoporomechanical behaviour of a fluid-saturated porous medium of infinite extent bounded internally by a fluid-filled cavity. The mechanical behaviour of the porous skeleton can either be Hookean elastic or elasto-plastic, with a constitutive response corresponding to a modified Cam Clay plasticity model. The fluid within the cavity can be subjected sim...
