Abstract Scope |
Lattices produced by AM continue to attract attention. The design tools which are available for these are somewhat limited and require expertise in their operation. A typical design strategy is to make use of the same unit cell which is patterned ad infinitum. This is at odds with similar structures observed in nature which have a degree of stochasticity. Here a novel way to design lattices more ‘naturally’ is presented. First, the same levels of stochasticity are applied to all parameters (Isotropic Randomness). Second, different levels of stochasticity are applied to each parameter (Anisotropic Randomness). Third, the stochastic level for each parameter is graded from regular to a given level of stochasticity (Graded Randomness). Fourth, a layer within the regular structure is randomised. Finally, stochasticity is applied to the surface to create a stochastic roughness pattern. This talk will explore our progress in developing this technique towards engineering application. |
