ETREMA Analyzes Magnetostrictive Materials with Simulation

Caty Fairclough | May 24, 2016

The magnetostrictive effect causes magnetic materials to change their shape when a magnetic field is applied. Materials that exhibit such behavior are used in a range of devices, from loudspeakers to actuators. In order to analyze one type of device, a magnetostrictive transducer, researchers from ETREMA Products, Inc. performed single-physics and multiphysics simulation studies in COMSOL Multiphysics. See how the flexible nature of the software enabled the team to study various aspects of the device and optimize its overall design.

Lasers, focused beams of photons of a single wavelength, find use in a wide variety of applications today — from noninvasive surgeries and fiber optic communication to material processing and even DVD players. Let’s see how a research team from Lawrence Livermore National Laboratory (LLNL) used the power of multiphysics simulation to investigate laser-material interaction to avoid the damage of optics internal to high-power laser systems.

Today, guest blogger Linus Fagerberg of Lightness by Design, a COMSOL Certified Consultant, shares how multiphysics simulation provides accuracy in automotive muffler design. The acoustic design of mufflers in the automotive industry has traditionally been performed by an iterative process where different alternatives are compared by experimental methods until a satisfactory design is found. Numerical simulation can drastically reduce a project’s time and expenses, while simultaneously increasing the performance of the muffler.

Pole vaulting is one of the most difficult events to master in track and field. Athletes must be able to run fast, be strong enough to elevate their body by holding the pole, and have excellent body control in order to change position while airborne. Analyzing the science behind this sport offers greater insight into the mechanisms that ensure success.

When designing tall, slender truss towers topped with heavy loads, engineers may want to account for buckling. This requires calculating the critical compressive load of the structure at hand. Simulation is a time- and cost-efficient way to generate such results. Now, with simulation apps, this process is becoming even faster. Those without simulation expertise can easily run their own tests to calculate the critical compressive load for different truss tower configurations.

By design, façades are meant to be visually appealing. Aesthetics, however, aren’t the only concern. It is also important to consider elements such as stability, efficiency, and comfort. Engineers at Newtecnic use COMSOL Multiphysics to strike this balance, creating façades that are both eye‐catching and functional.

Studying fish locomotion enables researchers to design vehicles and robots that can skillfully navigate aquatic environments. Performing such studies requires fluid-structure interaction (FSI) analyses of the fish and their environments. Using COMSOL Multiphysics, researchers from the Università Roma Tre were able to simulate carangiform swimming, a type of fish movement, and accurately evaluate its dynamics.

In structural mechanics, you may want to specify user-defined material models in your simulation. COMSOL Multiphysics® software version 5.2 enables you to access material models derived from external libraries as well as material functions programmed by yourself. We demonstrate how the new functionality works with the example of implementing Mazars’ model to describe damage to concrete.
