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.
Why Should You Simulate Fatigue?
The Fatigue Module, an add-on to the Structural Mechanics Module and the COMSOL Multiphysics® software, can be used to perform structural fatigue life computations for both strain-based and stressed-based fatigue. In this blog post, we discuss some of the potential application areas and benefits of fatigue testing.
Fatigue — When Cyclic Stress Produces Fractures
Many of the products that engineers design experience cyclic stresses during use that are below the material’s yield stress; unfortunately, these stresses can still be the primary reason for failure. Thus, engineers and designers must find ways of including the effects of cyclic stresses when designing products for long-term use.
The Stresses Subsea Cables are subjected to
In these days of globalization, keeping the world connected is imperative. Information needs to pass as freely and quickly as possible in order to keep markets up-to-date with the latest news and to ensure that commerce can be conducted without hindrance (at least of the technical kind). So what do you do – look to the sky? The answer is no; in fact, 99% of this information is carried by undersea cables. These unsung heroes sit at the bottom of […]
