Strain-rate dependent compressive properties of inverted honeycomb lattice and bulk cylindrical samples 3D printed by MSLA method
Original language description
Masked Stereolithography (MSLA) is an additive manufacturing process based on the photocuring of an entire printed layer of resin at once with the use of a UV light source, in this case a monochrome LCD display. The prints can be used not only for visualization of structures and parts, but also for development of elements of real constructions. The main objective of the study is to describe the mechanical properties under different types of loading, in particular to analyze the strain-rate sensitivity of compression response in bulk and inverted honeycomb lattice samples with three different strut widths. The specimens were experimentally investigated under quasi-static and high strain rate loading. Split Hopkinson Pressure Bar (SHPB) apparatus was used for the high strain rate experiments. The experiments were observed with a high-speed camera to allow analysis of the deformation processes. Digital Image Correlation (DIC) software was used to evaluate the displacement and stress fields. The results revealed a strong effect of strain rate, especially between quasistatic and high strain rate loads. An auxetic behavior was observed for the inverted honeycomb structure, which depends on the thickness of the struts.
