Original abstract
The aim of this work was to monitor the behaviour of 316L stainless steel produced by 3D printing. The material was tested in the state “as printed”. Digital Image Correlation measurements were used for 4 types of notches. The behaviour of these notches under monotonic loading was investigated in two loading paths – tension and torsion. Based on experimental data, two material models were used in finite element analyses. Subsequently, the load-deformation responses of simulations and experiments were compared. Ductility of 3D printed specimens in “as printed” state is also compared with 3D printed machined samples and samples produced by conventional methods.

Cílem této práce bylo monitorovat chování korozivzdorné oceli 316L vyrobené 3D tištěním. Materiál byl testován ve stavu “tak, jak byl vytištěn”. Měření digitální korelací obrazu byla použita pro 4 typy vrubů. Chování těchto vrubů při monotónním zatěžování bylo zkoumáno ve dvou zatěžovacích cestách – tah a krut. Dva modely materiálu byly použity v konečnoprvkových analýzách na základě experimentálních dat. Následně byly porovnány odezvy zatížení-deformace simulací a experimentů. Houževnatost 3D tištěných vzorků ve stavu “tak, jak byly vytištěny” je také porovnána s 3D tištěnými obrobenými vzorky a vzorky vyrobenými konvenčními metodami.
