The recent development of metal additive manufacturing makes it possible to manufacture lattice structures with complex
topology. The lattice structures can be applied to biomaterials, shock energy-absorbing parts, and thermal management components.
In this article, two studies related to strut-based lattice structures are introduced. One is the improvement in energy absorption
properties of lattice structures based on experiments and finite element analyses. A strategy for suppressing shear band deformation,
which has a detrimental effect on the energy absorption properties, is introduced. The other is an analysis for heat transfer properties
of lattice-structured heat sinks based on computational fluid dynamics simulation and machine learning. A methodology to
understand important structural features for heat sink properties is explained.
