In solid mechanics, there is considerable interest in achieving “invisibility”. The applications in mechanics include protection of structures and parts of structures from potentially harmful transient waves and steady state vibrations. A suggested large scale application is that protection against seismic waves from earthquakes could be achieved by using cloaking to re-route the waves around ...

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 ...

Internal combustion engine components have been a main research interest over many decades. The structural mechanics and dynamics of the piston rings has been a large focus of work in order to gain a greater understanding of the how the piston ring dynamics affect the piston ring. Piston rings are often coated to reduce the level of wear on the ring as they will suffer substantial levels of ...

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 ...

Describing and predicting the extent of the physicochemical processes as well as geometrical deformation taking place during food transformation is of major importance to control food functional properties. Unfortunately, only a few food-matrix models consider deformation particularly because of large deformation. In the case of a starchy product such as rice, water transport and swelling ...

It is commonly recognized that careful thermal design of electronic equipments represents an unavoidable pre-production step in order to ensure reliability and performance of those components during their functioning. This paper mainly concerns a comparison between experimental and numerical results obtained in studying thermal dissipation in natural and mixed convection conditions for RAM ...

COMSOL Multiphysics 4.0 is being used to simulate the free vibrations of a plate. The results obtained by simulation in COMSOL are in close proximity to that found by Fast Fourier Transform analyzer and analytical method. As of now the vibration analysis of thin rectangular plates with perforations in rectangular pattern has been carried out. The study of vibration analysis of thin ...

Two bimorph array facing opposite to each other are designed and attached with metal micro plates. The micro solar cell (or) film can be placed on the top of each plate for storing the energy. With respect to the direction of sun light, one bimorph array receives more energy in the form of heat than the other and deflects accordingly. The deflection of the bimorph array depends on the material ...

Nematic Elastomers (NEs) possess both the elastic properties of rubbers and the orientational properties of liquid crystals. Those two properties makes the configuration of NEs very sensitive to isotropic-nematic phase transition. Our goal is to replicate with numerical experiments the phenomena of shape formation in Twist-Nematic Elastomers (TNEs): a flat bar evolves into a helicoidal shape ...
