摘要

This paper describes improvements in a three-dimensional finite element model of the human female urethral tube. The preliminary model took into account the composite structure of the tube, the internal fluid pressure, external constraints and external active opening forces. However, the representation of external boundary constraints and fluid-solid interaction was relative crude. An improved version of the model is presented in the current paper, in which boundary conditions are taken into account in a more realistic fashion. The predicted behaviour of the tube is compared with X-ray photographs of actual urethral tubes. It is shown that the model captures the key features of the opening process.
