Video Tutorial: Introduction to the Structural Mechanics Module
The Structural Mechanics Module has numerous capabilities, enough for a video containing all of them to last days. This video demonstrates one of the many mechanical capabilities of COMSOL Multiphysics, by outlining a Static Linear Analysis. The chosen physics interface for this problem is Solid Mechanics, one of 13 physics interfaces in the Structural Mechanics Module. The video shows step-by-step how to set up the model of a bracket with a standard workflow (i.e. import the geometry, create global parameters […]
Industry: Continuum Blue Simulates Structural Mechanics
On January 10th, hundreds of people tuned in to hear COMSOL and Continuum Blue discuss Structural Mechanics simulations in certain industry applications. As promised in my previous blog post on multiphysics modeling webinars happening in 2013, here is a round-up of the event — including a video excerpt detailing three structural analysis examples presented by Continuum Blue.
Modeling a Pratt Truss Bridge
The simple design of a Pratt truss bridge makes it useful to hold everything from pedestrians to trains. While this type of bridge is easy to construct, engineers must make sure that it lasts and is safe to use. A bridge needs to hold its own weight, support the load placed upon it, and withstand frequencies generated by wind and earthquakes. To determine whether a Pratt truss bridge design can handle these factors, we turn to simulation.
Simulation-Based Design of New Implantable Hearing Aids
Growing older is an inevitable part of life, and with it, our body slowly begins to show that. I recently started wearing eye glasses because my eyesight is weakening. It’s a little unnerving, but I am comforted by the ever-improving technology being produced. My hearing is still fully intact, but the same cannot be said for 17% (36 million) of American adults who report some degree of hearing loss. In most cases, regular hearing aids are sufficient in treating hearing […]
First Keynote Video Takes Us to Babel
One of the differences between this year’s COMSOL Conference, and previous years’, is that this year we filmed a lot of it. During the next few weeks we will be publishing some of these videos for those that were there, to enjoy it once again, and for those that weren’t to get a taste of what went on. To kick these all off, I’m proud to present the first keynote video, which takes us to Babel.
Proprietary Code or Off-the-Shelf?
Many engineers and scientists have worked in their chosen application areas for many years. It is not unusual that their first models consisted of a few lines of code that they wrote themselves. Or, the application was so specific that the engineer was forced to write code, as none of the commercial simulation packages available could handle their unique application. Then there’s the COMSOL Multiphysics® software, which enables you to enter your own equations. What’s the best option?
The First Flyer Optimized Using Multiphysics
December of 1903 marked the commencement of the Age of Powered Flight, and the Wright brothers went down in history. This was a time before personal computers and simulation software existed. Determining the optimal design of their airplane had to be done using physical prototypes and real-life experiments. What had the design looked like if the Wright brothers had been able to use computers and modeling software? Three researchers from Pennsylvania State University sought to find out how the design […]
FSI: Aluminum Extrusion Model
Out of all metals, the most frequently extruded is aluminum. Aluminum extrusion entails using a hydraulic ram to squeeze an aluminum bar through a die. This process will form the metal into a particular shape. Extruded aluminum is used in many manufacturing applications, such as building components for example. The process of shaping metal alloys, like aluminum, can be modeled using COMSOL Multiphysics.
