Abstract
Photocured elastomers are widely used as 3D-printed structural materials due to their outstanding extensibility. However, their fracture behavior under different loading rates remains poorly characterized. Here, we conducted extensive experimental tests to investigate the rate-dependent mechanical behavior of a typical photocured elastomer – TangoPlus FLX 930. We applied thermal analysis to analyze its constituents and uniaxial tension tests to characterize the mechanical behavior of the elastomer from quasi-static to moderate strain rates and showed an increase in both fracture strain and stress of TangoPlus with increasing applied strain rate. To further investigate its time-dependent fracture behavior, we conducted relaxation tests under different strain and strain rates.
