A COMSOL® App to Determine Stress Distribution throughout Shelves
The goal of the work was the creation of a simple application using COMSOL Multiphysics® Application Builder allowing shelves static simulation. The application was created as an example of the possible use of COMSOL for customers without deep knowledge of COMSOL system and the Finite ... En savoir plus
Finite Element Modeling of Dispersion and Thermal Noise in Whispering-Gallery Mode Cavities
This work is dedicated to exact numerical modeling of modal dispersion and thermal noise in arbitrary cylindrical symmetric WGM structure. We develop a method and compare the results with experimental data from literature. We show that the real form of the resonator makes small influence ... En savoir plus
Simulation of Hydrogen Transport and Hydrogen-Induced Damage of High-Strength Steel Concepts
The prediction of material damage induced by hydrogen transport mechanisms is a major challenge for the development of new steel concepts. Especially the ultra-high strength steel concepts (UHSS), like dual phase and martensitic steels, can exhibit a higher vulnerability to hydrogen ... En savoir plus
Modeling and Simulation of Piezoresistive Pressure Sensor for 2bar Application
In this paper, we focused on modeling of the piezoresistive pressure sensors. The Structural Mechanics Module of COMSOL Multiphysics® software is used to model the sensor and make a comparative study of the MEMS pressure sensor with different shape and size of membrane. The impact of ... En savoir plus
Finite Element Evaluation of the Strength of Silicide-Based Thermoelectric Modules
Silicide-based thermoelectric modules (TEMs) for power generation operate at mid-high temperature range. In the operating conditions, thermal stresses in materials with different coefficient of thermal expansion may reduce the mechanical strength of the modules. In this work, a finite ... En savoir plus
Modeling Wear of Journal Bearings
Wear in hydrodynamic journal bearings resulting from solid contact in the mixed friction regime becomes an increasingly prominent topic leading to the necessity of numerical wear evaluations. A numerical method tackling this topic based on Archard’s wear law is presented and applied on a ... En savoir plus
An Elastohydrodynamic Lubrication Model Considering Surface Roughness and Mixed Friction
Highly loaded lubricated machine elements such as gears or camshafts are an integral part in a wide variety of technical products. Due to higher efficiency requirements these machine elements have to be improved continuously, which leads to the necessity to investigate physical ... En savoir plus
Finite Element Modeling of an Aluminum Tricycle Frame
As a sustainable urban transport system, the tricycle might represent an adaptive mobility vehicle used to transport people and bulk load. This transport system must warranty the security of its end users, then experimental and modeling works are very useful tools in order to evaluate ... En savoir plus
Numerical Vibration Analysis of Impacted CFRP Specimens Using COMSOL Multiphysics® Software
The vibration behavior of carbon fiber reinforced composites (CFRP) specimens with impact damage is presented in order to evaluate if an before/after modal analysis can be used as a non-destructive testing method to detect delaminations. The impact damage is modeled by decreasing the ... En savoir plus
Investigation of Low Energy Impact on Aeronautical Composite
Composite behavior when undergoing to low energy impact has been investigated thorough modelling and simulation computation. We consider the dynamic impact among a small granular material piece and a large composite material body. Really, our investigation will to simulate the ... En savoir plus
