Graphene, carbon atoms arranged in a two-dimensional hexagonal lattice has sparked tremendous research and application interests since its experimental discovery about two decades ago. Besides being ultrathin, this material exhibits a plethora of interesting properties, including high ... En savoir plus
High Cycle Fatigue (HCF) of a spoke in a wheel rim is studied. As the wheel rotates, the stress histories in the structure will become nonproportional. The risk of fatigue is evaluated using the Findley criterion. En savoir plus
In a lithium metal battery, lithium metal is deposited during charging on the negative electrode. Mass transport and ohmic effects in the electrolyte cause small protrusions on the metal surface to be subjected to accelerated growth during charging. In worst case scenarios, this leads to ...

COMSOL Multiphysics provides an interactive meshing environment where, with a few mouse clicks, you can easily mesh individual faces or domains. Each meshing operation is added to the meshing sequence. The final mesh is the result of building all the operations in the meshing sequence. ... En savoir plus
This model analyzes the nonlinear transfer impedance of a tapered orifice that can be part of a perforate or microperforated plate (MPP). The analysis is carried out for various degrees of tapering of the perforate and for a frequency range. A linear analysis is set up in the frequency ... En savoir plus
This model shows how to simulate carburization and quenching of a steel gear. Diffusion of carbon into the surface of the gear affects the onset of martensitic transformation. Residual stresses are computed, and it is shown that high residual compressive stresses appear at the root of ... En savoir plus
In static mixers, also called motionless or in-line mixers, a fluid is pumped through a pipe containing stationary blades. This mixing technique is particularly well suited for laminar flow mixing because it generates only small pressure losses in this flow regime. This example studies ... En savoir plus
A Helmholtz coil is a parallel pair of identical circular coils spaced one radius apart and wound so that the current flows through both coils in the same direction. This winding results in a uniform magnetic field between the coils with the primary component parallel to the axes of the ... En savoir plus
This example demonstrates the wrinkling of a thin rectangular sheet stretched uniaxially. First, a static analysis is performed to determine the region of negative principal stresses without wrinkling. Next, a prestressed buckling analysis is carried out to find out the linearized ...

A piezoelectric transducer can be used either to transform an electric current to an acoustic pressure field or, the opposite, to produce an electric current from an acoustic field. These devices are generally useful for applications that require the generation of sound in air and ... En savoir plus
