Abstract:
Sandwich panels can be subjected to significant changes in ambient temperature, which develop and sustain over certain time periods and lead to creep of the core material, and consequently to changes in the internal stresses and deformations with time. This paper deals with this issue with focus on the geometrically nonlinear aspects of structural behaviour. A theoretical model is developed, which combines the concepts of the principle of superposition of viscoelasticity, with the high-order sandwich theory (HSAPT), and the temperature dependency of the viscoelastic material properties.

Abstract:
Renewable energy resources such as wind and solar are intermittent, which causes instability when being connected to utility grid of electricity. Compressed air energy storage (CAES) provides an economic and technical viable solution to this problem by utilizing subsurface rock cavern to store the electricity generated by renewable energy in the form of compressed air. Though CAES has been used for over three decades, it is only restricted to salt rock or aquifers for air tightness reason. In this paper, the technical feasibility of utilizing hard rock for CAES is investigated by using a coupl

Abstract:
Once all construction materials have been formulated, it is necessary to find a suitable environment in which to store them before using them in the building. Generally speaking, in developing countries, materials are not preserved under the real conditions of temperature and humidity and are exposed to often severe climatic conditions. This has an impact on the behaviour of these materials. With this in mind, we conducted our study on concrete and cement bricks, the two materials most commonly used in building construction in Africa. The overall objective of our study is to analyse the effect

The resulting composite is produced as foam concrete and tested for a series of physico-mechanical, thermal and microstructural properties.

AbstractA possible solution to reduce the consumption of fossil fuel and energy demand to power heating and cooling devices is represented by Phase Change Materials (PCMs). They can absorb, store and release energy according to their physical state that changes with the environmental temperature. In this work, novel eco-sustainable PCMs were developed through the form-stable method. Through this process, it was possible to create composite PCMs consisting of a natural inert matrix (i.e., a very porous stone obtained from processing waste) and an eco-friendly polymer, i.e., Poly-Ethylene Glycol

Thermo-mechanical contact and micro-wear of head disk interface (HDI) are investigated using the improved HDI contact model and theories of frictional heat generation and heat transfer. In analytical simulations, dynamic contact parameters such as material properties, sliding velocity, and surface interference are based on actual HDI design and operation. The resulting contact pressure and temperature distribution show that the micro-wear on the carbon film of a head slider would be significantly attributed to the degradation of carbon material caused by frictional heat generation during slidi

Abstract:
A numerical technique for analysis of heat transfer and thermal distortion in reciprocating sliding components is proposed. In this paper we utilize the Arbitrary Lagrangian Eulerian (ALE) description where the mesh displacement can be controlled independently from the material displacement. A stationary and a moving component are modeled respectively as Lagrangian (mesh displacement equals material displacement) and Eulerian (mesh is fixed in space and material moves through the mesh). The description of the contact between both components accounts for frictional heating and heat exchange.

Abstract:
In Heat Assisted Magnetic Recording (HAMR), various thermal loads (laser, electrical current) subject the Head-Disc Interface (HDI) to intensive thermal strain / stress fields. The thermal strains, in terms of slider protrusion and media protrusion, significantly reduce the head-disc clearance and may lead to head-disc contact. Air bearings, by design, can passively adjust the fly height through so-called “self-compensation” to the protrusions. In this paper, an electro-thermo-mechanical model coupled with air bearing model has been developed to analyze the head flying characteristics under th
