建立了一种新的材料模型，用于研究具有工程缺陷的柔性生物可降解薄膜的变形和破坏。通过对具有多个缺陷（狭缝）结构的张力进行周动力学模拟，证明了这种新方法。模拟首先在不允许材料失效的情况下进行，以研究变形模式。然后检查了两个不同的临界拉伸值的破坏模式。确定了水平和垂直间距值对分离狭缝和狭缝布置的影响。这一研究证明了周期动力学方法在具有制造缺陷的结构参数化研究中的适用性。
A new material model within the peridynamic framework was implemented to study the deformation and failure of flexible biodegradable films with engineered defects. The new approach was demonstrated by performing peridynamic simulations of a structure under tension with a number of defect (slit) configurations. The simulations were first performed without allowing failure in the material to study deformation patterns. The failure patterns were then examined for two different critical stretch values. The effects of horizontal and vertical spacing values separating the slits, and slit arrangements were identified. This study demonstrated the suitability of peridynamic approach for parametric studies of structures with manufactured defects.
