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.
MultiMechanics will demonstrate the newly-released composite tube and pressure vessel optimization tool at CAMX 2018. The optimizer combines genetic algorithms and the ability to accurately represent microstructural damage within advanced materials to allow for automatic design of high performance composite tube structures, streamlining the engineering design loop.
MultiMechanics is partnering with Solvay and ANSYS to produce the webinar "How Solvay Uses MultiMech for ANSYS to Optimize Material Performance." The webinar will take place on Thursday, August 30th at 8:00AM CST.
MultiMechanics is excited to announce the release of MultiMech 18.1. The new features added will deliver improved ease of use, faster speed, and more simulation capabilities, including:
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.
Failure in engineered materials is extremely difficult. In composites, damage originates at the microscale and is then propagated to the global scale. While Finite Element Analysis is a powerful tool, it is limited to the global scale because the mesh refinement needed to get down to the microscale is not feasible in FE programs. At MultiMechanics, we consider this to be a true multiscale problem, since damage at the microscale needs to be assessed and relayed to the macroscale.
As we mentioned in Part I, the history of Finite Element Analysis is deeply intertwined with the evolution of computing. It seems only fitting that the FEA software used to design the world's most cutting-edge products should have the most cutting-edge computational techniques at its disposal. From the early punch days of the 60's through the 2000's, FEA companies have found unique ways to take advantage of the ever-changing computer landscape.
The first patent for computer software was filed in 1968 by Applied Data Research for a number sorting system. That same year, MSC Software, in partnership with NASA, released the first version of their now famous "NASA Structural Analysis" software (NASTRAN).
