The silicon diaphragm is one of the most common structures in Micro-Electromechanical Systems (MEMS). However, it is susceptible to creep deformation at elevated temperatures. This paper presents a transient finite element model which simulates the mechanical behavior of the ... Mehr lesen
Nanorobots may be used in the advancement of medical technology, healthcare, and environment monitoring by swimming in biological fluids flowing in narrow channels of a few hundred nanometers in the area of bio-medical engineering. The pronounced effects in nanometer scale such as ... Mehr lesen
In this paper describes an original method for indirect measurement of the vapor pressure and temperature in the keyhole in electron beam welding. This method is based on the determination of the concentration of chemical elements in the vapor above the welding zone. Taking into account ... Mehr lesen
In this paper a pre-study on using COMSOL Multiphysics for rotordynamic analysis is presented. It is concluded that it is possible to use COMSOL Multiphysics to perform rotordynamical analysis. However, there are no standard environment for rotordynamics, hence the user has to extend the ... Mehr lesen
During the hydraulic fracturing process, there can be possible re-activation of closed/sealed faults and natural fractures in the formation, which may lead to changes in the boundary conditions of the reservoir. While study models of shale gas formations have utilized the concept of a ... Mehr lesen
Campi Flegrei caldera is a good example of the most explosive volcanism on the Earth, a potential source of global catastrophes. It has the advantage that the most interesting structural details and main volcanic features appear located at shallower depth, making it a natural candidate ... Mehr lesen
We used COMSOL Multiphysics 4.3 to simulate the 2D elastoplastic deformation and plastic strain in a wedge-shaped plate above a subducting interface. The modeling results reveal that a pair of conjugate normal faults would first appear in the thinner part of the plate. Subsequently, a ... Mehr lesen
The understanding of quench, or the sudden transition to the normal state of a high-current Superconductor (SC), is fundamental for the design of a SC magnet, and it is widely discussed in the literature. This paper presents some simple COMSOL models, which are compared with well-known ... Mehr lesen
We have developed micro/nano machines such as optically driven micro/nano pumps and spiral-shaped piezoelectric vibration energy harvesters. COMSOL Multiphysics has been used for the design and development of the micro/nano machines. For example, optical force affected to a metallic ... Mehr lesen
INTRODUCTION: Micro Electro Mechanical Systems (MEMS) are fabricated with an in-plane fabrication technology. Out-of-plane structures can be designed to be assembled to provide thermal and electrical isolation from the substrate [1 -3]. These isolations can potentially improve the ... Mehr lesen
