Product of the Month

MSC Software Corp., Newport Beach, CA, announced the release of Marc 2015 nonlinear and multiphysics simulation software. Enhancements include new material models to simulate complex dynamic behavior of elastomers, permanent deformation of thermoplastics, and anisotropic plastic deformation in metal forming. The software provides a cohesive contact behavior that allows users to apply a finite stiffness in the normal and tangential direction, improving stress results in the contact zones and the overall deformation. A new family of elements has improved bending behavior compared to traditional lower order triangular and tetrahedral elements, and can be used for either compressible or nearly incompressible behavior. Two new global adaptive meshing methods are included, as well as improvements to Mentat, the user interface of Marc.

Products of Tomorrow: January 2016

The technologies NASA develops don’t just blast off into space. They also improve our lives here on Earth. Life-saving search-and-rescue tools, implantable medical devices, advances in commercial aircraft safety, increased accuracy in weather forecasting, and the miniature cameras in our cellphones are just some of the examples of NASA-developed technology used in products today.

Next-Generation Electronics Innovations for NASA’s Space and Commercial Future

In 1964, NASA’s Electronics Research Center (ERC) opened in Massachusetts, serving to develop the space agency’s in-house expertise in electronics during the Apollo era. The center’s accomplishments include development of a high-frequency (30-GHz) oscillator, a miniaturized tunnel-diode transducer, and a transistor more tolerant of space radiation. Another development was in the area of holography. At the ERC, holography was “used for data storage, and has permitted a remarkable degree of data compression in the storing of star patterns.”

Editor's Choice: January 2016

A miniature, low-mass vehicle is driven by a piezoelectric stack that generates ultrasonic vibrations that are transmitted through the vehicle walls. This eliminates the need to use gears or bearings, and avoids shafts or cabling through the vehicle wall. The transferred power can be used to activate sensors, and the motors are also selfbraking. The vehicle wheels or legs can be driven through the vehicle wall without perforating the structure, which is critical in harsh environments. Find out more HERE.

Supercomputers Help NASA Understand Booster Separation

NASA’s new heavy-lift launch vehicle, the Space Launch System (SLS), will carry three times the payload of the space shuttle, requiring innovative rocket design. The SLS configuration consists of a center core stage with four RS-25 engines and two solid rocket boosters (SRBs) that separate from the core as fuel is exhausted soon after liftoff.
