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 induced damage. The main reason for this is the complex microstructure, including a large number of several ...

The thermal management of silicon detectors and related electronics through micro-structured silicon cooling plates is gaining considerable attention for high precision particle trackers. Micro-fluidic circuits are etched in a silicon wafer, which is then bonded to a second wafer to obtain a cooling circuit. Because mono-crystalline silicon is structurally close in characteristics to brittle ...

Uncertainty in COMSOL Multiphysics® software simulations due to (a) model parameter uncertainties and (b) mesh-induced truncation errors, is estimated using a design-of-experiments approach [1, 2, 3], and a nonlinear least squares logistics fit method [4, 5], respectively. Examples to illustrate both approaches are given using the COMSOL RF Module (in an application of a MRI coil design) and ...

Thermal elastohydrodynamic lubricated (TEHL) contacts occur very frequently in drive technology and thus in gear drives. In this presentation, the implementation of a finite element based TEHL simulation approach for gear contacts in COMSOL Multiphysics® software is shown. The physically based simulation approach used is different to most of the existing TEHL simulations and is required to ...

The use of high power microwave energy for ablation of contaminated concrete is a promising technique to speed up the dismantling of nuclear power plants. A coupled simulation using COMSOL Multiphysics® finite element software is performed by solving the electromagnetic wave equation at 2.45 GHz for a standard wave guide and a concrete block. The temperature field is obtained with the heat ...

During Physical Vapor Transport (PVT) growth of single 4H-SiC crystal and subsequent cooling down, thermal stresses lead to the multiplication of dislocations that are non-desirable for the semiconductor applications of this material. These dislocations induced by thermal stresses could be reduced by an appropriate control of the thermal gradients inside du crystal during its growth and cooling ...

Due to the advantages of induction heating as a method for precise and efficient local heating, it is perfectly suited for thermal shrink fitting of a gear wheel on a shaft. In this work, a simulation model was established to study the induction heating of a gear wheel, its thermal expansion as well as the shrink fitting process. It was possible to find an appropriate geometry for the induction ...

The aim of this paper is to determine the location of the “sweet spot” for a selected cricket bat commonly used in the sport. Knowledge of the “sweet spot” is important in delivering a shot that utilizes the optimal zone of the bat that corresponds to the maximum power of the stroke. A model of the cricket bat was constructed in the Structural Mechanics Module of COMSOL Multiphysics® Software ...

For the SAFARI Imaging Spectrometer, part of the SPICA satellite payload, a Calibration Source is under development. Challenges in the design include the low cooling power (few mW) available at cryogenic temperatures. COMSOL Multiphysics® simulations were used extensively in the design process of the calibration source, allowing optimization of the thermal, electro-magnetic and mechanical ...
