A constitutive law for degrading bioresorbable polymers [PDF]

Journal of the Mechanical Behavior of Biomedical Materials, 2016
This paper presents a constitutive law that predicts the changes in elastic moduli, Poisson's ratio and ultimate tensile strength of bioresorbable polymers due to biodegradation. During biodegradation, long polymer chains are cleaved by hydrolysis reaction. For semi-crystalline polymers, the chain scissions also lead to crystallisation.
