Controlling Surface Chemistry and Morphology to Promote or Prevent Adhesion

We encounter interfacial interactions every day. Our tires grip the road because frictional forces between the rubber and concrete prevent tires from slipping. Conditioner moisturizes hair because it is designed to make contact with each strand to deliver moisturizing agents that separate the strands. Not unlike these interactions, the ability to controllably alter interfacial or adhesion interactions is important for a wide variety of industries from aerospace to marine to space exploration. To control interfacial interactions, both surface chemistry and topography play vital roles.

Cloud Engineering Tools Make Design Decisions Less Cloudy

The main purpose of engineering software is to help engineers make smarter decisions faster and to avoid sacrificing quality for speed. Cloud technology dramatically improves access to information and people, enabling faster decision-making by you and your engineering team, thanks to the ease of which information is accessed. This webinar, given by the founders of two successful providers will focus on the application of cloud technology in engineering software and its impact on decision-making in two key areas: component selection & change management.

Why Does Your Product Break?

Fatigue is often cited as one of the most common forms of operational failure in structures. Its nature is an often apparently premature failure at relatively low, but cycling, stress levels.

High-Performance, Thermally Insensitive Optics

Silicon Carbide has a unique set of thermal and mechanical properties that make it an ideal material for some reflective optics systems. The difficulty of manufacturing lightweight structures with SiC, however, has limited its use to substrates attached to benches made of more forgiving materials.

Fluid Structure Coupling Technology

NASA Marshall Space Flight Center's Fluid Structure Coupling (FSC) technology is a highly efficient and passive method to control the way fluids and structures communicate and dictate the behavior of a system. Developed to solve a difficult structural dynamics issue of a national asset, an FSC device weighing less than 200 lbs successfully mitigated a potentially detrimental resonant response of this 650,000 lb structure.

Multiphysics Flow Simulations

Computational Fluid Dynamics (CFD) is central to many multiphysics analyses – either to determine the fluid flow itself or as the convective mode for other physics. This webinar will explore laminar, turbulent, and multiphase flows as they interact with structures (FSI), electromagnetics, heat transfer and mass transport. We will demonstrate how easy it is to model and simulate CFD applications with COMSOL Multiphysics. The webinar will conclude with a Q&A session.

Predicting Fatigue Failure to Increase Operational Availability

As we enter an era of reducing new equipment procurement coupled with a constrained spending environment, the sustainment community is under significant pressure to increase the life and operational availability of existing and aging assets with a flat or reduced budget.
