目前广泛使用延性金属网作为碳纤维增强复合材料（CFRP）的雷击直接效应防护手段。在防护设计中，为了在加强防护效果和减轻部件重量之间取得最优设计，需要研究被防护部件铺设不同规格延性金属网时的电流和温度分布。但延性金属网的网格尺寸与被防护部件尺寸之间的存在巨大差异，精细建模时需要大量计算资源。本文对延性金属网建立一体化的雷击热损伤等效模型，推导出等效模型所需要的电导率、热容、导热系数、密度等参数，并将等效模型计算结果与试验结果进行对比。对比结果表明：本文所用的等效仿真方法可以有效反映各规格金属网的烧蚀程度，铺设金属网能提供有效的雷击直接效应防护 ... Mehr lesen
Negative Refractive Lens (NRL) has shown that an optical system can produce images with details below the classic Abbe diffraction limit. This optical system transmits the electromagnetic fields, emitted by an object plane, towards an image plane producing the same field distribution in ... Mehr lesen
Neuromodulation is the use of electromagnetic fields to modulate the human nervous system, typically to treat neurological disorders. Electroceuticals is an ambitious program to modulate any nerve, anywhere, anytime, for any reason — to treat disease, disorders, and enhance or interface ... Mehr lesen
The Finite Element Method (FEM) has become an established numerical tool used for different academic and industrial purposes. It allows the prediction of weld pool geometry, thermal cycle, final distortion and residual stress field during and after fusion welding. The capability of the ... Mehr lesen
A scientific hypothesis states that cryogenic trapped water is just under the surface of lunar soil at the poles in permanently shadowed craters. Microwave energy can be used to efficiently extract this water from permafrost. COMSOL permits calculation of the heating of simulated lunar ... Mehr lesen
Arcam AB has pioneered additive manufacturing using the electron beam melting (EBM) technology which provides a cost efficient and novel way of producing titanium components for the orthopedic and aerospace industries. In the heart of the EBM technology is the electron beam – whose ... Mehr lesen
Permanent Magnet Flowmeter (PMFM) is a non invasive device, which is used to measure the flow of electricallyconducting sodium in Fast Breeder Reactor Circuits. PMFM works on the principle of generation of motional EMF by magnetic forces exerted on the charges in a moving conductor. In ... Mehr lesen
This paper presents the mathematical modeling for the analysis of the magnetostrictive materials, which describes the behaviour of the magneto-mechanical coupling in a rod of magnetostrictive material and capturing it in COMSOL® to produce a predictive and detailed analysis. A simulation ... Mehr lesen
