Spectrum Materials Engineering LLC also has extensive experience with lightweighting. This experience includes not only the materials engineering side, but the geometrical design side as well. This has led to the publication of papers, university level lectures and a book chapter. Specific areas of expertise include:

  • Materials design to maximize strength and stiffness to density ratios

  • Topology, topometry, topography and shape optimization

  • Efficient joint design

  • Numerical optimization and design space search algorithms
