MULTIPHYSICS DIGITAL TWIN OF A NONLINEAR TPMS‑GRADED BIODEGRADABLE BONE IMPLANT
A mathematical model and computational implementation of a digital twin for a bioresorbable polylactide (PLA) bone scaffold with a functionally graded triply periodic minimal surface (TPMS) architecture are developed. The model comprises four state variables (polymer mass, osteoblast population, growth factor concentra...
