Abstract
This work deals with quasi-static and dynamic fracture behaviors of Additively Manufactured (AM) ABS coupons. In this research, planar specimens have been additively printed using a heated circular nozzle producing a continuous bead of 0.2 mm diameter and 0.2 mm layer thickness in the build directions. Of specific interest to this work is the role of two different print architectures namely 0/90° and ± 45° in-plane orientations. The local measurement of in-plane displacements are performed optically using DIC up to crack initiation and during growth in quasi-statically loaded 3-point bend specimens and impact loaded edge-notched specimens. The latter set of experiments are carried out using an instrumented Hopkinson pressure bar and an ultrahigh-speed digital camera. Significant differences in the engineering parameters and failure modes as a result of the build variables and loading rates are observed.
