| Abstract Scope |
Internal lattice structures have the potential to significantly reduce the mass of an existing metal component, which is a desirable characteristic in the aerospace and automobile industries. However, there are still uncertainties on whether or not internal lattice structures can outperform a solid version of the same mass. Additionally, internal lattice structures can only be produced via additive manufacturing methods, bringing more challenges to resolve. To determine the viability of internal lattice structures, a study will be performed to compare its mechanical properties with solid, hollow, and mass penalty designs of equivalent masses using Autodesk Fusion 360. A performance baseline will be established by running multiple simulations on simple geometries to obtain the maximum displacement, first four modes, and first buckling mode. A generative design part, better known within NASA Goddard Space Flight Center as A15, will undergo the same simulations and have its results analyzed to determine feasibility. |
