A unit truss finite element analysis method allowing non-linear deformation is employed to
analyze a unit cell comprised of n
3
octet-truss structures for their stiffness and displacement
compared to their relative density under loading. Axial, bending, shearing, and torsion effects are
included in the analysis for each strut in the octet-truss structure which is then related to the
mesostructure level (unit cell). The versatility of additive manufacturing allows for the
fabrication of these complex unit cell truss structures which can be used as building blocks for
macro-scale geometries. The finite element calculations are compared to experimental results for
samples manufactured on a Stereolithography Apparatus (SLA) out of a standard resin.Mechanical Engineerin
