| Abstract Scope |
Recent experiments at Brookhaven National Laboratory’s, National Synchrotron Light Source II, will be highlighted in which we implemented an in situ load cell capable of tomographically imaging a specimen during uniaxial loading. Instead of requiring minutes/hours to collect the 3D images, as in the laboratory, multiple (>36) 3D images can be collected per second. We no-longer need to pause the in situ compression/imaging experiment and now can begin to explore the effects of strain rate upon a 3D materials response. We will showcase the 3D compression deformation of various AM polymer lattices (both structures and materials) at strain rates between 0.25 and 2.2 /s during 3D tomographic imaging. With this technique, we can image the bending, buckling, cracking and failure of the materials, in 3D, at various strain rates and explore how subsurface features (voids) can be investigated to understand the structures response to better inform our material models. |
