Numerical Investigation of Ti6Al4V Gradient Lattice Structures with Tailored Mechanical Response

Open porous lattice structures have found a wide range of applications as lightweight load‐bearing and energy absorbent in various fields. A common requirement for any application is the preliminary assessment mechanical response proposed architecture. Herein, uniform continuous functionally graded (FGLSs) made titanium alloy, Ti–6Al–4V, are designed using cubic pillar octahedron unit cells at overall porosities 60%, 75%, 85%. The morphology modulated axial, dense‐in, dense‐out gradient strategies. performance studied numerical simulations implementing damage initiation evolution under quasi‐static compression. models could properly simulate properties failure behavior structures. FGLSs displays crushing starting from lower relative density layers toward higher ones. Cubic octahedron‐based exhibit stretch‐ bending‐dominated deformation behaviors, respectively. power‐law analysis verified by Gibson–Ashby model used to assess FGLSs. effect strategies on well their adaptability orthopedic implants discussed detail.
