This example demonstrates the modeling of a sandwiched composite blade made up of carbon–epoxy, glass–vinylester, and PVC foam materials. Three different methods are used to model the sandwich composite structure: Layerwise theory, Equivalent Single Layer (ESL) theory, and a multiple ... En savoir plus
This model analyzes a piezoelectric microelectromechanical system (MEMS) speaker. The speaker, composed of four triangular membranes, uses a layer of lead zirconate titanate (PZT) material with two electrodes on top of a silicon layer as actuators. The triangular membranes are separated ... En savoir plus
These examples demonstrate how to generate randomized geometric surfaces. Note that there is now also an add-in covering random surface functionality for planar surfaces. The COMSOL Multiphysics® software provides a powerful set of built-in functions and operators, such as ... En savoir plus
This example demonstrates how you can use modeling to investigate the performance of different hydrodynamic journal bearings. The model uses the Hydrodynamic Bearing interface, which solves the Reynolds equation to compute the pressure developed in a thin fluid film for four different ... En savoir plus
This benchmark demonstrates how to use the Beam interface in the Structural Mechanics Module. It calculates the deformation, section forces, and stresses in a cantilever beam as well as a number of eigenfrequencies. It also illustrates how to use the Beam Cross Section interface to ...
