Every vehicle operates in a constant state of flux. Not only must a car’s engine produce the necessary energy to propel the vehicle forward; its battery must also provide power to operate various electronic devices (sensors, radio, touch-screens, etc.) within the vehicle. These components, in turn, operate at different frequencies requiring constant DC to AC conversion. Electronic components must also withstand incredible temperature variation within a vehicle’s interior, from subfreezing to well over 100 degrees Fahrenheit.

User-defined materials provide the flexibility needed to design models using a combination of existing material properties and properties defined by the user. These material properties can also be included in a user-developed material database for easy access to frequently used materials. Users often spend significant time developing models with material properties not available in the

Medical device designers are responsible for many of the life-saving and life-enhancing therapies relied on by patients worldwide. From pacemakers to ablation tools to imaging devices, much of our current medical treatment would be impossible without the dedication of these engineers. But with the push to innovate comes a consistent pressure to develop new therapies

Radio Frequency Identification (RFID) technology has been around for more than 50 years and continues to evolve. Today, the technology uses electromagnetic fields to automatically identify, and track tags attached to both inanimate objects and living creatures. The great appeal of RFID technology is that unlike bar codes, it allows information to be stored and

Many of the simulations we have developed through the years include materials that behave anisotropically. This class of materials has different material properties in different directions. This anisotropy often needs to be included in computational models to achieve the desired level of accuracy in the simulation outputs. If the material coordinate system of the anisotropic

Thermal stresses are an important design concern for many engineering applications. When temperatures change, materials can deform or warp leading to the build-up of internal stresses even without the presence of external constraints which can further increase thermal stresses. Modeling and simulation can calculate the deformations, stresses and changing contact pressures using thermal-structural interaction techniques.

Many engineers solve heat transfer challenges regularly. Over the last 20 years, AltaSim has developed hundreds of simulations for our clients that include heat transfer as a component. This Tip comes from our experience in solving a heat transfer problem that included thin layers of different materials. Solid elements are the most widely used type

The increasing miniaturization and sophistication of electronic products–ranging from consumer media devices, to medical diagnostic tools, to defense-related sonar applications–presents a bounty of utility and ease for consumers, and an ongoing challenge for design engineers. These seemingly disparate products (audio/mobile device speakers, certain non-invasive medical devices and sonar arrays) share in common a reliance on
In Part 1, we provided a basic introduction to Piezoelectric materials. In this blog, we will take a look at specific products that present a challenge for design engineers due to the need for increased output within smaller devices. Mics and Speakers Piezoelectric materials are used extensively in acoustics. Microphones contain piezoelectric crystals that convert
