MultiMechanics has been selected as a finalist for three industry awards: the Mondial.Tech Startup Award, the CAMX Award, and the Award of Composites Excellence (ACE). These awards recognize technologies that are shaping the future of composites and transportation.
The analysis of composites and other heterogeneous materials is complex for a number of known and very well-documented reasons.
Multiscale modeling is a broadly used term to describe any situation where a physical problem is solved by capturing a system's behavior and important features at multiple scales, particularly multiple spatial and/or temporal scales. Applications for multiscale analysis include fluid flow analysis, weather prediction, operations research, and structural analysis, to name a few.
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.
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.
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).
