Plasma spraying is one of the prominent technologies for wear, corrosion and high temperature resistant coatings. The coating quality is very important to increase the performance of the components as well as to protect the outer surface of the component from external environment. The coating quality characteristics depend on many plasma process parameters. Among these parameters, distribution ...

Different facilities for hadrontherapy have been built in the recent past. AISHa ion source has been designed by keeping in mind the typical requirements of hospital-based facilities, where the minimization of the mean time between failures (MTBF) is a key point together with the maintenance operations which should be fast and easy. The study of some critical parts of the facilities: the ...

The Finite Element Model is analyzed with impounded water considering appropriate boundary conditions between the water & the upstream face of the dam .The fluid on the upstream side is considered to be incompressible, inviscous, and irrotational. Here the effect of fluid compressibility is analyzed by the use of COMSOL Multiphysics® software. The impact of water pressure on the upstream face of ...

Nowadays, to go along with sustainable development and for cost matters, automotive heat exchangers are built with less and less aluminum and the process costs are being cut. However, the real mechanical response is a plastic shakedown, which is why we need to model the cyclic response as well as to find a fatigue criterion. A finite element model was developed using COMSOL Multiphysics to ...

A 3D thermo-mechanical simulation was developed using COMSOL Multiphysics software in order to predict distortion of a welded dissimilar titanium alloys structure. An angular distortion and a longitudinal shrinkage are predicted in agreement with those obtained experimentally.

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 ...

It is very difficult to measure the global properties of heterogeneous and anisotropic materials like composites and sandwich structures. When designing composite sandwich applications, the elastic properties are required to perform structural stiffness and strength calculations. However, due to their anisotropic nature, it is not straightforward to measure these properties with traditional ...

Lamb waves are elastic waves propagating in free solid plates. In the case of plates loaded with a fluid, the equations describing these waves have to be modified to include the effects of the fluid. In our work we have tackled this problem using COMSOL Multiphysics®. We have used the two-dimensional plane strain model of the solid mechanics interface to calculate the eigenmodes of the coupled ...

The use of high-resolution topography in the finite element model demonstrates that deformation from a shallow pressure source can be dramatically affected by overlying relief, not only in magnitude, but also in azimuth. This result is significant as it allows traditionally anomalous data to be evenly weighted during inversions for magma reservoir parameters. The result that surface ...

A hyperelastic seal is pulled over a metal ring in a coffee machine for maintenance reasons. The force needed to pull the hyper elastic seal over the part is too high and should be reduced for maintenance reasons. Using the COMSOL Multiphysics® Structural Mechanics Module, and using the non-linear hyperelastic for the stick slip movement, a reliable simulation was generated. It resulted in an ...
