Hierarchical lattice structure
Web14 de set. de 2024 · Although the hierarchical lattice was optimized for plane stress conditions using linear buckling theory, and for an infinite periodic material, it proved to perform excellently, in terms of compressive load capacity, in a real 3D structure with a finite number of unit cells and with nonlinearities included. WebThis, of course, is where hierarchical lattices produced by additive manufacturing come to the rescue. Lattice structures have the highest energy absorption performance, sound/vibration dispersion, and impact protection while maintaining the smallest volumetric footprint and weight possible. As electrification and self-driving cars gain greater ...
