The coupled heat and moisture actions could easily cause deformation, cracking corrosion problems in the slab ballastless track under operational conditions via China Railway Track System (CRTS) Ⅱ. In this paper, two one-quarter-scaled models of CRTS Ⅱ hygro-thermal environment were tested a testing chamber, respectively. To study effect constrained on structural performance structure, temperat...

This paper describes recent efforts made by the Danish Building Research Institute regarding the integration of a life cycle assessment (LCA) method into a whole building hygro-thermal simulation tool. The motivation for the work is that the increased requirements to the energy performance of buildings (as expressed in EU Directive 2002/91/EC), may in the future be supplemented by requirements ...

The multiple coupling of composite laminates has a unique advantage in improving the macro mechanical properties structures. A total three hygro-thermally stable multi-coupled with extension-twisting were presented, which conducive to formation passive adaptive Then, used design bending-twisting coupled box structure, configuration laminate and structure could be extended variable cross-section...

Brucella melitensis, as a pathogenic gram-negative intracellular bacterium, causes brucellosis in animals and humans. According to literature, the B. melitensis outer membrane protein 31 (Omp31) is considered as an important vaccine candidate against brucellosis. The aim of the current study was to compare three different expression constructs containing B. melitensis Omp31 antigen using bioinf...

This paper presents our effort to predict IC, packaging, and board level reliability problems. Micro-electronic based reliability problems are driven by the mismatch between the different material properties, such as thermal expansion, hygro-swelling, and/or the degradation of interfacial strength. In the past, such reliability problems were treated separately, but recent development have made ...

The paper proposes an analytical model for calcium leaching of concrete due to water. The model is set in the framework of chemically active saturated porous media. Continuum damage mechanics is used in order to develop a phenomenological poroplastic model of concrete. Two forms of damaging processes are included: mechanical, modelled with two scalar damage internal variables; chemical, related...

The effects of microwave and steam treatment were analyzed relative to the immediate (thermo-hygro-plasticity) post-assessed (permanent changes) properties wood. study was conducted using European beech (Fagus sylvatica L.) standard 1.5 times up-scaled (only for microwave-heated reference samples) bending specimens tested in a static three-point loading mode. plasticized by heat moisture (1) se...

concrete deformation due to temperature and moisture condition will always develop simultaneously and interactively. the environmentally (hygral and thermally) induced stress and deformation are essential to concrete durability. to simulate the deformation of concrete caused by the coupling effect of temperature and moisture, a numerical simulation approach is proposed comprising analytical pro...
