Introduction: Solver section of FEA plays a very important role; it takes the input from the preprocessor and solves millions of equations using numerical methods. Capability of any analysis tools can be measured based on the solver. Understanding the nature and operation of various structural solid mechanics solvers is the interest of the present study. Results: Contact pressure is ...

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 ...

Using COMSOL Multiphysics® software, a new model was implemented with the Physics Builder functionality, which provides a thermomechanical coupling. It consists of two independent physics interfaces, one for the mechanical, viscoelastic behavior and one for the heat transfer. With the multiphysics coupling features it is now possible to add the effects of thermal expansion and dissipation or ...

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 element evaluation of the mechanical strength of a 16 legs thermoelectric module prototype operating with 300 K ...

This paper presents the modeling and simulation of electro-thermo-mechanical self-oscillators, an emerging type of M/NEMS-enabled timing devices in which sustaining electronic amplifiers are not required for their operation. Indeed, they realize amplification in the mechanical domain and feedback by crossing three physical domains: electrical, thermal and mechanical. In a previous work , we ...

Puffing of biomaterials involves mass, momentum and energy transport along with large volumetric expansion of the material. Development of physics-based models that can describe heat and moisture transport, rapid evaporation and large deformations can help understand the puffing process. In this context, a fundamentals based study of salt-assisted puffing of rice is described. A multiphase model ...

The high flow rate within the HFIR cooling water flow channel causes the fuel plates to deflect which in turn, changes the coolant flow characteristics. This nonlinear feedback loop between the coolant and the fuel plate is the focus of the present simulation of the fluid-solid interaction between the coolant flow and the fuel plates to accurately predict the plate’s deflection using the Fluid ...

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 ...

Energy efficiency and harvest, speed and performance, flexibility and portability are key elements for innovation in the current consumer electronics markets. Thermoelectric Generators can convert energy from heat gradients into electricity. Every source of heat from an electronics device can potentially be used as a source of energy. This generators have the advantage of: being silent, compact, ...
