A modelling-simulation-analysis workflow for investigating socket-stump interaction

The lack of an efficient scientific framework that simplifies the analysis of socket-stump interaction is one of the key reasons why physics-based socket modelling techniques are not prevalent. Herein, we propose a novel scientific framework that generates detailed subject-specific 3D models of the stump, containing muscle fibre anisotropy, in less than 20 minutes. The generated model is analysed under bipedal stance and dynamic gait conditions using a continuum-mechanical damage model, which predicts soft tissue stresses. Upon comparing a state-of-the-art stump model with the proposed detailed model, it is evident that both stresses are underestimated by the state-of-the-art models.
