Human Urinary Bladder as a Soft Biological Shell

Abstract

In Chap. 3, we have demonstrated that the urinary bladder satisfies all the hypotheses and assumptions of the theory of thin soft shells. Furthermore, the wall of the organ, its geometry, and stress–strain distribution within it can be approximated, with a sufficient degree of accuracy, by the middle surface of the organ. Contractions in the bladder are triggered by underlying electrical events in the detrusor. The basic anatomical and morphological data can be summarized as follows:
