Résumé :
[en] This paper presents a new method for optimizing the thickness distribution of a functionally
graded lattice structure. It links the thickness of discrete lattice regions via mathematical functions,
reducing the required number of optimization variables while being applicable to highly nonlinear
models and arbitrary optimization goals. This study demonstrates the method’s functionality by
altering the local thickness of a lattice structure in compression, optimizing the structure’s specific
energy absorption at constant weight. The simulation results suggest significant improvement
potential for the investigated Simple Cubic lattice, but less so for the Isotruss variant. The energy
absorption levels of the physical test results closely agree with the simulations; however, great
care must be taken to accurately capture material and geometry deviations stemming from the
manufacturing process. The proposed method can be applied to other lattice structures or goals
and could be useful in a wide range of applications where the optimization of lightweight and
high-performance structures is required
