In this article, vibration characteristics and the parametric instability of functionally graded material (FGM) plates with cyclic loading in a hygrothermal field are discussed. The plate element is modeled in a finite element by applying the third-order shear deformation hypothesis. The mathematical formulation of the FGM plate is made with two material constituents by applying the power rule ...

The current energy crisis and the necessity to minimize waste suggest need assess non-air-conditioned buildings in terms of install an air-conditioning system size control it efficiently. This applies historical museum hosting artworks that require specific microclimate conditions for their preservation. With this view, work analyzes suitability properly preserve exhibits. Therefore, two museum...

Several methods for appropriate control of the hygrothermal environment in museums to prevent deterioration cultural artifacts were presented previous studies. However, few detailed simulation models have been used considering performance building components and airflow through gaps. Furthermore, properties a type storage facility with buffer spaces prevailing Japan not quantitatively evaluated...

The main objective of this paper is to highlight the research works being carried out on the hygrothermal behaviour of building materials and wall systems at the National Research Council (NRC) Canada. The paper depicts selected results obtained from parametric studies conducted on wood frame stucco walls commonly used in Canadian climatic conditions, using hygIRC, an advanced hygrothermal mode...

Abstract Indoor air humidity evaluation plays an of great importance role on the thermal comfort and building energy consumption. The utilization hygroscopic materials as acts indoor by regulating its fluctuations, then reduces a certain fraction consumption conditioning systems. Based Fick’s law, physical process inside these requires determinations hygrothermal properties, which signify exten...

A mathematical model for the description of drying shrinkage of autoclaved aerated concrete (AAC) is presented, bringing together the hygrothermal and mechanical considerations. The verification of the model is done using an approximation of a real laboratory experiment. Then, the applicability of the model is demonstrated by a numerical simulation of drying shrinkage and wetting expansion of A...

This paper presents the development of a simulation tool based on the Matlab computational environment for building temperature performance analysis with automatic control. The simulation tool contains mathematical models for buildings, HVAC (Heating, Ventilation and Air Conditioning) systems, sensors, weather data and control algorithms. The building mathematical model is described in terms of...

The viability of a novel sustainable polymeric composite material, based on photocurable linseed oil resin was explored, with a view to exploiting its potential in marine environments. The study focused on a UV-curable resin subjected to setting through photoinitiated cationic polymerisation. Deployment of heterogeneous solid catalysts, containing isolated Brønsted acid centres, further improve...
