OpenLattice, a user-friendly software package that streamlines lattice generation, homogenization, and topology optimization. OpenLattice facilitates the design of TPMS, strut-based, and auxetic lattices, capabilities that are rarely available in existing software, and integrates homogenization-based topology optimization (HMTO) to reduce computational effort and enhance precision compared to conventional approaches reported in the literature. The package provides four core functionalities: (1) lattice generation, (2) homogenization, (3) homogenization-based topology optimization (HMTO), and (4) reconstruction of functionally graded lattices for validation and manufacturing purposes. Researchers can leverage HMTO results to create functionally graded lattices beyond the capabilities of current tools, enabling tailored mechanical performance that is often unattainable with previously reported software.
OpenLattice enables the generation of three distinct classes of lattices: TPMS, strut-based, and auxetic lattices. In this chapter, a common TPMS modeling approach is summarized, while a newly developed method for creating strut-based and auxetic lattices is presented.
The homogenization method enables to simplify explicit lattice geometries into implicit bulk geometries with effective material properties. This approach reduces the computational cost of modelling explicit lattice geometries which require a large number of mesh elements.
OpenLattice can also perform HMTO to enable functionally graded lattice structures (FGLs) to take full advantage of lattice structures by enhancing their mechanical performance. OpenLattice utilizes unit cell homogenization to determine the scaling law of corresponding cellular structures. Each term of the elastic constant for CH can be expressed as a polynomial function of the relative density of cellular structures.
The team is open to sharing the source codes with other researchers or research groups for collaboration purposes. This openness fosters collaboration, allowing for continuous improvement and adaptation of the software to meet the evolving needs of the academic and research communities.
OpenLattice is a software package with a user-friendly interface that simplifies the design of optimized lattice structures. It offers 3 main modules: lattice generation, homogenization, and topology optimization.
