In this paper, the effect of a crack to the flow-induced vibration characteristics of supported pipes is investigated based on vibration method. In order to estimate the crack location and depth in the pipe, we need to utilize the variation of the difference between the natural ... En savoir plus
Carbon dioxide levels are increasing faster than in hundreds of thousands of years due to fossil fuels burning. A serious worldwide interest is growing towards the field of CO2 valorization as a step in transitioning away from fossil fuel economy at the same time of decreasing CO2 ... En savoir plus
The numerical results of the unconfined compression test on a sample of Articular Cartilage (AC) are discussed. AC is modelled as a load-bearing, deformable, fiber-reinforced material filled with an interstitial fluid and comprising statistically oriented collagen fibers, chondrocytes, ... En savoir plus
The vibration of an electrodynamic loudspeaker driver causes a resulting sound pressure. For simple pistonic vibration, there is a simple relationship between the vibration and the sound pressure. For complex vibration patterns, however, different parts of the vibrating surface ... En savoir plus
Benchmarks are important tools to verify computational models. In the research area of building physics, the so-called HAMSTAD (Heat, Air and Moisture STAnDardization) project is a very well known benchmark for the testing of simulation tools. In this paper we revisit this benchmark by ... En savoir plus
This document has been produced by Washington River Protection Solutions, LLC on behalf of the Department of Energy (DOE) for the use of COMSOL when simulating applications related to DOE's waste management. COMSOL has been classified as a grade D acquired software program and this ... En savoir plus
Electromagnetic force and density in the electric-machinery dynamic system are fundamental forces which cause physical phenomena such as structural deformation, vibration, noise etc. But when two materials are contacted, electromagnetic contact force and distribution by conventional ...

In general, seamount magnetic modeling assumes uniform magnetization for the entire construct. The following geologic obervations are often not considered: 1. The internal structure composed of multiple volcanic layers, and 2. Remanent magnetization gained during the magnetic polarity ... En savoir plus
Thermoelectric (TE) devices generate electrical potential when they have temperature difference. Silicon is one of the materials applied to TE devices. However, most of the studies about TE silicon devices have focused on 1D structure, like Si nanowire, not on 2D. In this study, silicon ... En savoir plus
최근의 수치모델링 연구들은 맨틀 플룸(mantle plume)이 배호(back-arc)지역의 분지 및 산맥(basin and range)과 유사한 지구조를 형성시키는 성인임을 제시하였다. 섭입 슬랩 후퇴(slab roll-back) 현상에 의해 지각에 가해지는 인장력과 지각 아래로부터 상승하는 뜨거운 맨틀 플룸으로 인한 지각 강도 감소가 더해져 배호 지역에 분지를 형성시킨다는 것이다. 이처럼 분지 형성 작용에 있어 맨틀 플룸의 역할이 중요해짐에 따라, 수치모델링의 필요성이 커지고 있기 때문에 초기 연구로써 ...
