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 ...

In this work the influence of the geometry of the Vickers indenter tip on relevant indentation properties is investigated during instrumented indentation operated in the macro range (i.e. with forces ranging from 2 to 200 N) and carried out in the case of a homogenized (i.e. heat treated) TiAl alloy. The instrumented macro-indentation test is simulated by Comsol Multiphysics using a full 3D ...

Resistive heating filaments used in high temperature applications at 2000°C and above are often made of refractory metals. The lifetime of such filaments is mainly limited by creep deformations which can in the worst case lead to a short circuit between filaments and other furnace components. With the aid of COMSOL Multiphysics software, the time-dependent creep deformation behavior of a heater ...

Manual wheelchair users suffer shoulder pain and injury in the long term because of unconscious overuse. The ‘SENSEWHEEL’, which interposes three identical load cells between pushrim and rear wheel, measures the three components of pushing force Fx, Fy and Fz, and axial torque Tx applied at each load cell. Strain gauges were located on a diaphragm forming one face of the load cell. The ...

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 ...

The dynamic behavior of cable supported bridges subjected to moving loads and affected by corrosion and accidental failure mechanism in the cable suspension system is investigated. The different types of cable supported bridges are distinctively characterized by the configuration of the cable system . The suspension system comprises a parabolic main cable and vertical hanger cables connecting ...

Electroplated CoFe alloys demonstrating Joule magnetostriction (i.e., a large change in material shape induced by an applied magnetic field) have been recently developed for the creation of microfabricated magnetoelastic resonators for tagging applications. This development requires a measurement technique for evaluating film magnetostriction performance to provide feedback for optimization of ...

As any other modelling of a physical behavior, the numerical simulation of the mechanical response of an adaptive secondary mirror requires that the results match the experimental data. Such an agreement was recently demonstrated for the local mirror stiffness of the LBT and VLT Deformable Mirrors; a reliable modeling is a good tool for the extrapolation of the missing optical data (spider ...

Cells are complex entities which not only passively sense external stimuli (viz. chemical, optical or mechanical) but also interact with extracellular matrix (ECM) by regulating cellular behavior such as growth, proliferation, migration, etc. Monitoring cell growth and migration of adherent cells becomes a crucial factor in determining cell-cell and cell-substrate interaction, important for ...
