High/low thermal conductivity materials can change temperature by transferring/blocking heat. To cool the asphalt pavement, alleviate rutting damage, and improve the urban heat island effect, heat transfer models and rutting models were established based on the finite element software ABAQUS, and ...
5.Duplicate the layer three times and change the rectangle colors.复制矩形层三次并改变每个层的颜色。 6.The accident buckled the wheel of my bicycle.那次事故撞得我的脚踏车轮子变了形。 7.Study on Daqingshan Ductile Deformation Zones of Lower Crust in Inner Mongolia;内蒙古大青山深层次韧性变形带...
where j corresponds to the jth material phase used in the design domain. 4.4.6 The Minimum Volume Change Limit Any change to the structural boundary due to the optimization process, will have an effects on the criterion distribution. The minimum volume change limit parameter (ΔVMinLim) or (...
The VDS split is based on the orthogonal decomposition of the strain tensor in spherical ∊∊S and deviatoric parts ∊∊D. Thus, the negative strain energy part is related to the spherical energy in a region with a negative volume change(12)∊∊ψ0-∊u=Ktr-∊22(13)∊∊...

The high phase change enthalpy released with solidification or absorbed with melting is the key feature of phase change materials (PCMs) such as paraffins. A new microencapsulation technology enables the containment of paraffins in microspheres with a polymethylmetacrylate - shell of about 5 ... 20...
PHASE change materialsCONCRETE mixingThe article presents selected types of phase change materials (PCM) and their properties in terms of applications in various fields of science such as construction and concrete technology. The aim of the article is to present a comparative analysis betwe...
MP/EG phase change composite was prepared and characterized in this research, and the heat transfer performance was numerical simulated by finite element analysis software ABAQUS. Results show that MP can be absorbed into the layered pores of EG, and the stable absorption ratio is 77%. Numerical...
In 2005, gold-based alloys were again at the center of a wide research campaign at the University of Minnesota. There, researchers outlined a set of theoretical requirements (cofactor conditions) for a phase-change material to be free of stressed transition states.23In principle, such a substanc...
The specific chemical composition of an α-β titanium alloy tends to change the volume fraction of α or β phase [23]. Firstly, the study is focused on the slip accumulation adjacent to the hard grains. As given in Fig. 1(b) and (c), the grains of interest are illustrated with ...
