What Is the Difference Between Plane Stress and Plane Strain?
We go over the formulations and constitutive models that you can use to study plane stress, plane strain, and generalized plane strain in your solid mechanics problems.
Building a Solid Foundation for Understanding Seismic Waves
In 1906, there was the California earthquake. In 1908, there was the Lawson Report. In 1910, Harry Fielding Reid proposed the elastic rebound theory. Continue on a deep dive into seismology…
Designing Cavity Filters for 5G Devices with Multiphysics Modeling
From radar and microwave ovens to particle accelerators, RF cavity filters are found in a variety of different application areas. Among them: 5G devices and infrastructure.
6 Examples of Simulation-Driven Loudspeaker Development
From headphones for virtual reality gaming to powerful transducers for hearing aids, here are 6 examples of multiphysics simulation being used to develop new and improved loudspeaker products.
How to Model a Hall Effect Sensor with COMSOL Multiphysics®
Basic working principle of a Hall effect sensor: A nearby magnetic field deflects the path of current through a semiconductive sensor, which causes a measurable change in potential.
Which Radiation Interface Should I Use for My Heat Transfer Model?
Compared to the mechanisms of heat transfer by conduction and convection, heat transfer by radiation has unique characteristics. How should you account for radiation in your heat transfer models?
A Quiet Revolution: Analyzing Electric Motor Noise via Simulation
The sound we hear from electric-powered machines is a multiphysics phenomenon: A motor’s electromagnetic activity sends vibrations through both the machine and the surrounding air.
Analyzing HIFU Propagation Through a Tissue Phantom
High-intensity focused ultrasound (HIFU) is used for surgery, cancer therapy, shock wave lithotripsy, and more. Learn about how simulation can be used to analyze this noninvasive technique.
