In this report, we present the design and analysis of microcantilevers of various shapes and materials for different applications. Here we investigate the sensitivity i.e. amount of bending of the cantilever due to same amount of force applied to each of the shape and the respective material using COMSOL Multiphysics software. In this context, we are restricted to the use of microcantilevers in ...

The use of thermoplastic materials is increasing and it is becoming more important during the design process to accurately represent the non-linear material response in relevant loading conditions. The COMSOL Multiphysics® software supports advanced modeling capabilities for large deformation analyses, including contact and multiphysics couplings. It is now also possible to use advanced non ...

The tensile strength of masonry is relatively low compared to its compressive strength and is affected by the direction of the joints and their filling. In masonry with modern thin layer mortar (joint thickness 3 to 5 mm) sometimes the head joints are left open. A total of 13 model-walls was built and for each model four general purpose mortar combinations and three thin layer mortar ...

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 ...

Graphene, a single layer of carbon atoms, has demonstrated extremely high electric and thermal conductivities, tensile strength, and is therefore an exciting novel building block in the world of 2D flexible electronics. We propose the integration of graphene with MEMS devices to investigate the strain dependence on graphene material properties, such as electrical and thermal conductivity, index ...

Powder metallurgy is a key technology for manufacturing advanced components based on TiAl alloys. Cold compaction is the primary step to produce green parts. Cold deformation of TiAl powder is difficult due to its typical poor ductility. Plastic deformation and cracking susceptibility of TiAl powder strongly depends on micro-mechanical phenomena. To manage real compaction problems more reliable ...

The Oak Ridge National Laboratory (ORNL) is developing technology to re-establish the capability to produce plutonium-238 for the National Aeronautics and Space Administration (NASA) as a power source material for powering vehicles while in deep-space. The High Flux Isotope Reactor (HFIR) of ORNL has been utilized to perform test irradiations of in-capsulated neptunium oxide (NpO2) and aluminum ...

COMSOL Multiphysics software was used to structurally optimize the Wright brothers’ flyer. The flyer was drawn in SolidWorks, imported and meshed in COMSOL. COMSOL Solid Mechanics module was used to analyze the flyer. Four of the sixteen struts were removed yet the structural integrity of the flyer was maintained. COMSOL Laminar Flow module was used to compute the aerodynamic forces and ...

In this work, we present the performance analysis of novel micro machined Piezoresistive fluid flow pressure sensor using COMSOL Multiphysics. The principle of the sensing mechanism is based on the deflection of four sensing layers embedded on a thin membrane. The fluid passes through the layer causes the deflection of the sensing layer which measures the pressure of the fluid. The following ...

To reduce friction in lubricated tribological contacts, the surfaces of the contacting bodies can be microstructured to improve lubricating conditions. For lower loaded contacts this approach has already reached industrial applications, e.g. the piston-liner contact. For higher loaded contacts the effects are currently in basic research. Elastic deformation in the contact area plays an important ...
