Abstract

The purpose of this study was to determine biomechanical properties of linea alba subjected to transverse planar tension and to compare its behavior at different locations of the abdominal wall. Samples of linea albafrom five different porcine abdominal walls were tested in planar tension. During these tests, strain maps were measured using thestereo-digital image correlation (S-DIC) technique. The strain maps were used to derive the properties of differenthyperelastic material models. It was shown thatthe Ogden model and the Holzapfel-Gasser-Ogdenmodel areappropriate to reproduce the response in planar tension. The linea alba located above the umbilicus was significantly more compliant than below the umbilicus. This differencewhich is reported for the first time here is consistent with the tissuemicrostructureand it is discussed within the perspective of clinically-relevant numerical simulations.
