10x Faster Finite Element Analysis of Injection Molded Parts. The Secret? Faster Mid-Surface Modeling and Meshing!

The process of creating midsurface geometry and finite element meshes of injection molded plastics such as automotive interior trim components, aircraft overhead bins, and electronic cases can require extracting dozens of planar and curved midsurfaces, adjoining specific free edges, meshing, and more. Unfortunately with existing finite element pre/post processors, the process can require multiple days to complete.

Phase Change Material (PCM) Heat Sinks: Fundamentals of Operation and Real World Applications

Phase Change Materials (PCMs) Heat sinks provide significant temporary thermal energy storage in an increasing number of military and commercial applications. PCM essentially take benefit from the latent heat required for the solid-to-liquid and liquid-to-gas phase transitions. When properly engineered for power and mission duration, PCM solutions can be used as passive, lightweight, reliable backups or standalone heat sinks.

Analysis of Automotive Adhesives Using FTIR Spectroscopy

In conjunction with SAE The automobile industry is under government regulation to improve the fleet fuel economy. Meeting this regulation will partly be realized by power train improvements, while a significant percentage will be achieved by reducing the mass of the vehicle fleet. Reduced mass will come from the use of lighter materials, notably aluminum, composites and plastics. These materials will require the use of adhesives for joining dissimilar materials, while maintaining strength and managing thermal expansion differences. The use of a variety of adhesives in the automobile industry will grow as new materials are adopted in the vehicle fleet.

Autonomous Vehicle Radar: Improving Radar Performance with Simulation

In conjunction with SAE Automotive radars must operate in complex and dynamic environments where interactions with the vehicle and its surroundings can have a significant impact on the performance of the radar system. In particular, material properties of the vehicle fascia and the radar’s location behind the fascia can impact its performance and must be accounted for by radar designers and system integrators.
