This paper presents an experimental study focusing on the fracture behavior of hydrogels, specifically examining the effects of water content. The methodology involves the development and implementation of an algorithm to analyze dynamic fracture and determine fracture energy. Experimental setups and procedures are detailed, and the results of the experiments are analyzed. The study provides pioneering insights into the dynamic fracture properties of PAAm hydrogel, offering experimental data that will contribute to future developments in hydrogel applications. Additionally, an algorithm capable of tracking crack tip velocity is proposed, providing an effective and affordable alternative to traditional analytical setups for future research use.
