Computational Modeling of Flexible Biodegradable Films with Engineered Defects

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.
