| Abstract Scope |
Microlattices are a class of man-made structures that are made of an interconnected network of struts, with advantages like high strength to weight ratio, outstanding energy absorption and negative Poisson’s ratio. Recent developments in the field of additive manufacturing of metals and polymers have enabled the fabrication of micro-architectures with tailorable properties with ease. In this work, novel multi-microlattice structures composed of multiple lattice unit cell geometries are designed and fabricated by additive manufacturing technique, and the quasi-static compressive behavior is studied. The multi-microlattice structures are found to excel in terms of compressive strength and energy-absorbing capability when compared to single microlattice. The modes of deformation of the multi-microlattice structures are studied, and buckling of the struts is found to be the prominent deformation mechanism. Along with experimental investigation, finite element analysis using Abaqus/Explicit is also carried out. |
