• Analysis of Mesostructure Unit Cells Comprised of Octet-truss Structures 

      Johnston, Scott R.; Rosen, David W.; Reed, Marques; Wang, Hongqing Vincent (Georgia Institute of TechnologyUniversity of Texas (Austin), 2006-08)
      A unit truss finite element analysis method allowing non-linear deformation is employed to analyze a unit cell comprised of n3 octet-truss structures for their stiffness and displacement compared to their relative density ...
    • Design of a Graded Cellular Structure For an Acetabular Hip Replacement Component 

      Johnston, Scott R.; Rosen, David W.; Wang, Hongqing Vincent (Georgia Institute of Technology, 2006-08)
      The state-of-the-art porous coatings become more and more popular in uncemented prostheses to make bone grow into implants for biological fixation. In this paper, graded cellular structures are proposed for uncemented ...
    • Design of General Lattice Structures for Lightweight and Compliance Applications 

      Rosen, David W.; Johnston, Scott R.; Reed, Marques (Georgia Institute of Technology, 2006-07)
      The primary goal is to design parts with lattice mesostructure and demonstrate that they have better structural and/or compliance performance, per weight, than parts with bulk material, foams, or other mesostructured ...
