Abstract
To take advantage of the toughness mechanism of double network hydrogel (DN gel) and explore its possibility for engineering application as the structural member, the information on the mechanical behaviour of DN gel under various loading conditions is indispensable. Therefore, in this study, we at first perform the cyclic compression test to clarify the dependence of the mechanical response of DN gel on the loading history and the loading speed. Continuously, we constitute a computational model to discuss the effect of triaxiality of the loading condition and the loading speed on the deformation behavior of DN gel with complicated shapes.
