Introducing the Composite Materials Module

Pawan Soami December 6, 2018

Composite materials are heterogeneous materials composed of at least two integrated components. Among the different types of composite materials, layered composite materials are quite common and are widely used for aircraft, spacecraft, wind turbine, automobile, marine, buildings, and safety equipment use cases. The Composite Materials Module, add-on to the COMSOL Multiphysics® software, includes built-in features and functionality specifically designed for studying layered composite structures. Fiber-reinforced plastics, laminated plates, and sandwich panels are a few common examples of layered composite materials.

Heart failure is a global health concern, affecting millions of people and keeping them from their everyday lives. But what if there was a device that could keep patients’ hearts pumping and even improve their quality of life? In his keynote presentation at the COMSOL Conference 2018 Boston, Freddy Hansen from Abbott Laboratories discussed a heart pump that could do just that. If you missed his talk, you can watch a recording of the video and read a summary below.

When modeling acoustic devices, it’s often enough to account for linear propagation alone, even though nonlinearities are always present. However, when the signaling amplitude reaches high levels in a design, nonlinear effects become important. Engineers can include nonlinear effects in simulations by taking advantage of the Nonlinear Acoustics (Westervelt) feature in the COMSOL Multiphysics® software, as demonstrated by an exponential horn example.

A pioneer in chemistry, sanitary engineering, and human ecology, Ellen Swallow Richards paved the way for women in science. She was the first woman to attend, graduate, and teach at MIT. During her career, she developed standards for water quality and isolated the chemical element vanadium. In addition, Richards was passionate about using science to create a better home life, founding the field of home economics.

There has always been a debate among engineers working with fluid flow about the suitability of finite element methods for CFD. Some engineers have a firm opinion about the superiority of finite volume methods compared to finite element methods. Is there a scientific support for this opinion? No, not in general. Different methods may be suitable for different problems. Let us see why.

Sir Horace Lamb was a British applied mathematician and professor who wrote several textbooks that became fundamental in physics. Among them is a comprehensive text that was considered the standard for hydrodynamics for many years. His work in this subject resulted in the Lamb vector, the Lamb-Oseen vortex, and Lamb surfaces. He also authored works on sound, statistics, and mechanics.

Plastic floating at sea often winds up in debris-filled gyres, commonly known as garbage patches. These patches of plastic circulating in the ocean pose a danger to wildlife and are slowly entering the food chain. One project aims to remove this debris with floating boom technology, which is often used to contain oil spills.

Did you know that the COMSOL Multiphysics® software allows you to have different discontinuous meshes in neighboring domains? Although the usual default behavior of the software is to use aligned meshes, there are times when we might like to have discontinuous meshes, such as for modeling conjugate heat transfer. Let’s delve deeper into this topic and see how these meshes can save us time and memory in our initial model development with just a little bit more effort.

“Equipped with his five senses, man explores the universe around him and calls the adventure ‘science.’” — Edwin Hubble Imagine if the entire universe consisted of the Milky Way galaxy alone. Most scientists thought this was the case before astronomer Edwin Hubble discovered other galaxies. Considered the founder of extragalactic astronomy, Hubble was one of the leading 20th-century figures in observational cosmology and provided evidence that the universe expands at a constant rate.
