Interfacial failure or delamination in a composite material can be simulated with a cohesive zone model (CZM). A key ingredient of a cohesive zone model is a traction-separation law that describes the softening in the cohesive zone near the delamination tip. This example shows the ... En savoir plus
The following example demonstrates techniques for modeling a fluid-structure interaction containing two fluid phases in COMSOL Multiphysics. It illustrates how a heavier fluid can induce movement in an obstacle using the arbitrary Lagrangian-Eulerian (ALE) technique along with the Two ... 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
Designing structures and open spaces with respect to sound quality is important for concert halls, outdoor environments, and even the rooms of a house. Simulating acoustics in the high-frequency limit, where the wavelength is smaller than the geometrical features, can be done with ray ... En savoir plus
Planar photonic waveguides in silica (SiO2) have great potential for use in wavelength routing applications. The major problem with this type of waveguide is birefringence. Anisotropic refractive indices result in fundamental mode splitting and pulse broadening. The goal is to minimize ... En savoir plus
In this model, a full transient analysis of a loudspeaker driver is performed, which allow the modeling of nonlinear effects. It extends the linear frequency domain analysis done in the Loudspeaker Driver tutorial model. The analysis accounts for nonlinear behavior of the soft iron in ... En savoir plus
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
Ultrasonic flowmeters determine the velocity of a fluid flowing through a pipe by sending an ultrasonic signal across the flow at a skew angle. When there is no flow, the transmitting time between the transmitter and the receiver is the same for the signals sent in the upstream and ... En savoir plus
The use of wave-based techniques for room acoustic simulations has spread in the last years due to the increase in computational performance as well as the development of new numerical methods. The challenge of including realistic impedance conditions at walls is traditionally solved in ... En savoir plus
The primary defense of a submarine lies in its capacity to remain hidden during operation. As radio waves are strongly absorbed by seawater, sound navigation ranging, or sonar, is one of the main methods used for the detection of submarines. Sonar systems are also used for underwater ...
