Flexible and semi-rigid polyurethane foams are widely used as noise and vibration damping materials. Their porous random microstructure is composed of a visco-elastic frame structure with an interstitial fluid, normally air, filling the voids. The viscoelasticity of the foams is due to ...

泄洪闸室结构具备挡水和泄水两重主要功能的水工建筑物，工作中因水位变幅较大，加之泄流振动的水流动水压力不断突变，尤其水工闸门的启闭过程所形成的缝隙流对闸室结构产生严重危害。为此，以大藤峡深孔泄洪闸室为研究对象，研究其结构应力应变特征。首先对COMSOL流固耦合有限元与PSO-BP神经网络两种方法进行重构形成研究方法，针对大流量泄洪闸室泄流振动条件的结构应力应变研究重构后的方法可以发挥两种方法的优势；然后以COMSOL开展闸室泄流水体与闸室结构的流固耦合有限元模拟，获得泄流激励条件下坝身振动特征与应力变形规律；随后构建PSO-BP神经网络分析模型，分别开展了创建网络结构 ...

The experience of the eruption in Montserrat in 1997 has shown that the resistance of openings of buildings represents a crucial factor in the evaluation of vulnerability to the stresses caused by pyroclastic flows, although the static nature of the building itself is not compromised. ...

Soil sedimentation and consolidation, whether they are naturally or anthropically driven processes, are closely interconnected. While theoretical models are available to separately describe the behaviour of either ‘fluid’ suspensions or ‘solid’ soil, no well-established unified theory ... Per saperne di più
Technologies based on micro electro mechanical systems (MEMS) present advantages for rheological applications as they enable the fabrication of smaller sensors with faster response times. In this work we propose fabrication parameters and simulation of a MEMS viscometer. This research ... Per saperne di più
Valves are widely used to control fluid flow in various engineering applications. It’s crucial to study the flow characteristics inside the valve and the fluid-structure interaction between the fluid and valve’s sleeve for design, optimization and improvement of valves. However, because ... Per saperne di più
The mitral valve apparatus is a complex and refined mechanism located between the left atrium and the left ventricle of the heart which can manifest various kinds of pathologies. In order to support identification of potentially critical conditions resulting from some typical ... Per saperne di più
COMSOL® models of basal body deformation using the Beam Interface are compared to electron tomograms of Tetrahymena thermophila basal bodies high-pressure frozen while undergoing beating deformation. This approach provides insight into the nanoscale structures and internal forces ... Per saperne di più
The material wood is frequently used in construction industry for several elements such as window frames. However, as a hygrothermal material, wood is sensitive to moisture induced damage. In this context, the moisture uptake of wood based windows logged with an integrated relative ... Per saperne di più
Temperature homogeneity is a critical issue for high temperature vacuum furnaces for heat treatment, as small temperature variations in the load volume can significantly influence the heat treatment result. It is generally defined by the so-called Temperature Uniformity Survey (TUS) ... Per saperne di più
