| Abstract Scope |
Metal additive manufacturing has enabled new applications in the area of lightweight, high stiffness metallic lattice fabrication. Load bearing properties, strength-to-weight ratio and tailored shock absorption are three mechanical benefits of the lattice structures. However, the deformation behavior of additively manufactured (AM) lattice structures is very complex and challenging to be predicted, in part because of the unique nature of AM materials. In this work, we present results of a multi-institutional effort aimed at characterizing the quasi-static and dynamic mechanical properties of metal lattices. In situ synchrotron diffraction and differential interference contrast measurements are performed with the aim of understanding the behavior of single cell Ti-5553 lattice structures under compression, which will permit improved design optimization of the lattice structures for specific applications. This work was performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344. |
