摘要：
Biodegradation polyester has a wide range of application prospects in medicine due to their good properties and biodegradability. The change of strength during the degradation process directly affects the situation of application, and the complexity of degradation makes the strength prediction more difficult. In this paper, after analyzing the influence factors of strength, the non-applicability of the representative strength model was proved by formula deduction, and then a heterogeneous phase strength model based on the multi-scale model of the degradation of biodegradation polyesters was proposed. Different strength equations were used in different polymer phases. The proposed strength model is coupled with the multi-scale model, the calculated results fit with experimental data very well, which indicates that the method proposed in this paper is correct and feasible. © 2018, Editorial Board of Polymer Materials Science & Engineering.
