Advancing Degradation Modeling in Biodegradable PLA Bone Plates and Vascular Implants With Abaqus Using VUSDFLD Subroutine

Hey there, curious minds! Are you ready to embark on a journey into the world of degradation modeling? Brace yourself as we dive deep into the fascinating realm of biodegradable implants. In this captivating video, I’ll unveil the secrets of modeling degradation in Biodegradable Vascular Stents and Bone Plates, using the incredible Abaqus software via VUSDFLD subroutine. Prepare to be amazed! 👨‍🔬💻

Our Elasto-plastic material model captures the properties of bone plates, stents, and bones, while a hyperplastic model replicates vessel behavior. With the implementation of VUSDFLD, we calculate degradation based on time and strain, guiding our understanding of the implants’ performance. ⏳📊

Fracture initiation in PLLA stents is determined by the element death criteria, ensuring accurate simulation. The element death criteria is as under “”. Once the maximum principal strain decreased to lower than the fracture strain, the fracture will be initiated in the PLA. This approach provides valuable insights into the implants’ fracture behavior and aids design optimization. 💥🔍
