Much attention has been given to the advent of long fiber thermoplastics due to their desirable recycling, manufacturing, and mechanical properties. However, the question remains as to whether current analysis tools and techniques can safely capture this material's behavior.
The analysis of composites and other heterogeneous materials is complex for a number of known and very well-documented reasons.

MultiMechanics and Fortify, a Boston-based additive manufacturing company specialized in composite material systems, have announced a strategic partnership to improve the predictability of composite 3D printing. As part of the partnership, Fortify will use MultiMechanics' flagship product, MultiMech, to predict the structural integrity of printed parts before printing, and to help optimize the design by controlling the fiber orientation throughout the structure. Additionally, R&D will be performed to further enhance Fortify's print analysis software, INFORMTM, and generate more sophisticated microstructures using their FluxprintTM process based on microstructure analyses performed in MultiMech.
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:
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.
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.
