- Bioresorbable implants, such as coronary stent, are a step change in medicine. Designing these implants using finite element analysis requires their constitutive laws. Unlike traditional engineering materials, the constitutive laws of biodegradable polymers have to deal with changes in molecular weight and degree of crystallinity. This paper for the very first time established such a constitutive law. This is a mechanism-based constitutive law. The paper shows that Young’s Modulus of degrading polymers can be predicted using a “cavity-based” theory and that this theory fits with all the experimental data that were independently obtained from different research groups.
