Due to their exceptional properties like high specific strength, high thermal conductivity, less weight and so forth, they are being used in various industrial applications like electronic packaging, and also in automobile, aerospace, defense sectors. Thus, this paper aims at producing a numerical model of micro machining of various compositions of Al-SiC alloys and studies the effects of various parameters on machining such composites.

Depending on the frequency, RF radiation can travel through solid insulating structures, typical atmospheric conditions, clouds, and rain with only minimal losses allowing for its use over long ranges and in varied weather conditions. The aerospace and defense industries have expanded and progressed rapidly as a result of using radar systems for detection and classification tasks to determine if an object or target is present, where it is located, and if it is moving or stationary. The prevalent use of radar in the defense industry has naturally created the need for detection avoidance methods in order to maintain a competitive edge.

As satellites and astronauts travel further out in space, the more communication challenges they are faced with. This article discusses the variety of antennas that can be found on a spacecraft and the different simulation techniques that are best suited for each type of antenna such as helical antenna, horn antenna, dish reflector antenna, and phased array antenna.

The residual stresses developed in a stiffened panel manufactured using Electron Beam Freeform Fabrication (EBF3) process were studied. EBF3 process is a layer additive process that can be used to build near-net shaped parts directly using computer controlled techniques, which can be used for aerospace structures.
A COMSOL model was created to simulate the residual stresses using a thermo-mechanical analysis, with the Goldak’s semi ellipsoidal moving heat source.

Stealth airplanes and ships avoid radar detection by optimizing the shape of surfaces to reflect away from the radar source or absorb its energy. Yet, if a ship or aircraft’s antenna for communication purposes is to operate properly, it cannot be completely covered up. This makes it one of the remaining components with a large radar cross section and can essentially destroy the overall system’s invisibility to radar.

Pressure Sensors are widely used in the automotive industry. Their main use is the dynamic monitoring of pressure inside combustion engines. To achieve a good signal accuracy, the design of pressure sensors can be improved with FEM calculations of stress and strains on the measuring cell depending on their geometry and material properties.
The geometry is adapted according to a special nominal pressure and a limit rule of the stresses.

FEM (Finite Element Method) modelling software such as COMSOL Multiphysics® can be a powerful tool for modelling the behavior and response of piezoelectric materials and devices [1]. Devices based on piezoelectric crystals are particularly well suited, because the polarization magnitude in crystals is predetermined and its orientation is defined by how it was cut with respect to the lattice structure. In the case of polycrystalline piezoelectric ceramic materials, the overall polarization vector in the material is not oriented in one single direction nor is constant all over the material.

Microwave drying processes are critical components in the manufacture of cellular ceramic substrates and filters. The objective of this study is to develop a comprehensive model at a small scale and include all the possible physics that are important during microwave drying processes. Based on the results, conclusions are made on the importance of different factors in drying.

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 the Structural Mechanics Module (in a stress analysis of a wrench). Significance and limitations of both methods are presented and discussed.

Micro-scale devices based on the Stirling cycle are an attractive choice for chip- and board-level electronics.
A new Stirling cycle micro-refrigeration system composed of arrays of silicon MEMS cooling elements has been designed. COMSOL is used to evaluate the thermal performance of the system. Simulation of compressible flow and heat transfer with a large deformed mesh has been successfully implemented and is used to determine the cooling capacity and coefficient of performance, COP.
