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.

How to Zoom Into Your Material Microstructure using ANSYS Workbench

Posted by MultiMechanics on Jun 6, 2018 8:00:00 AM

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.

Solvay and MultiMechanics Partner to Reduce Material Development and Certification Cost

Posted by MultiMechanics on May 30, 2018 8:00:00 AM

Improving efficiency, lowering emissions, and decreasing fuel consumption are global trends that are currently transforming the transportation industry. Lightweighting by replacing metal components with lighter composite materials is one approach to achieving these goals. However, as structural designs have become more complex and demanding, new composite material development has struggled to keep up, thus slowing the adoption of lightweighting.

A Brief History of Finite Element Analysis - Part II

Posted by MultiMechanics on May 16, 2018 8:00:00 AM

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.
