Filament Wound Pressure Vessels & Space Shuttle Disasters

Posted by MultiMechanics on Oct 31, 2018 8:00:00 AM

One of the most visible symbols of American ingenuity and exploration over the past 50 years has been the progress and perseverance of the National Aeronautics and Space Administration (NASA). It is the epitome of human curiosity. It is a constant example of how we live with unknowns for only as long as technology limits our ability to explore; and sometimes we try and explore those unknowns before technology is ready.

Physical Testing vs Multiscale Virtual Simulation of Advanced Materials

Posted by MultiMechanics on Oct 24, 2018 8:00:00 AM

The transportation industry is increasingly adopting advanced materials, which, as a result of increases in specific strength, offer improved efficiency, lower emissions, and decreased fuel consumption compared to traditional metal components. However, the transition to advanced materials has been slowed as structural analyses have become more complex and demanding.

MultiMechanics and Opterus R&D Partner to Create Advanced Material Models in Response to NASA Solicitation

Posted by MultiMechanics on Oct 17, 2018 8:00:00 AM

MultiMechanics and  Opterus R&D, a Colorado-based satellite component manufacturer specializing in the design and testing of deployable space structures, have announced a collaboration in response to a NASA Solicitation seeking further exploration of the use of thin-ply High Strain Composites (HSCs) for space applications. These advanced composites have the potential to reduce weight and increase performance of space systems, but they exhibit behavior that is difficult to predict using currently available Finite Element Analysis (FEA) tools.

Thin-ply HSCs are being used by Opterus in several commercial, NASA and DoD missions that achieve unprecedented packaging and deployed stiffness performance. Compared to traditional composites, HSCs exhibit improved damage tolerance, resistance to microcracking, improved aging and fatigue resistance, reduced minimum-gage thickness, and increased scalability.

The Anatomy of a Composite Microstructure

Posted by MultiMechanics on Jun 20, 2018 8:00:00 AM

Microstructural modeling is often viewed as an extraneous activity when analyzing the behavior of composites. Many engineers use the "system" properties as the inputs for their part design without considering what contributes to that overall system response.

3 Reasons Why You Should Perform Multiscale Finite Element Analysis

Posted by MultiMechanics on Jun 13, 2018 8:00:00 AM

Many companies that develop new composite materials are surprised when their product does not perform as expected during the physical testing and certification process. In addition to the many years wasted on developing the material, companies often spend more than $50M on developing and testing a single new material concept.
