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).
