Abstract
Fracture behavior of Shape Memory Polymers (SMPs) and their self-healing property is one of the up-to-date subjects through the literature, where only a few researches have been conducted. Nowadays, because of the exceptional properties of SMPs and their implementation in 4D printing, they are most taken into attention. In this study, thermomechanical coupling effect on 3D fracture analysis of SMPs in large deformation regime has been investigated. Firstly, a thermo-visco-hyperelastic model is implemented to model the thermomechanical cycle of the SMP in the stress-free strain-recovery as well as the fixed-strain-stress-recovery processes. Motivated by fracture analysis and self-healing properties of SMPs, both 2D and 3D fracture analysis are conducted through various feasibility applications, such as flow control valve, pressure control valve, filtration and drug delivery capsule. Moreover, the ability of the analysis is shown through examining different parameters could affect the SMP response, such strain rate (or applied strain), temperature rate and memory recovery. Finally, the results show the ability of the numerical modeling in the aforesaid applications to design, analyze, and fabricate these applications.
