 This study characterizes the tensile properties of the human abdominal wall by layer and as a partial composite through uniaxial tension testing on fresh never-frozen and fresh frozen cadavers. The results show variations in tensile properties within and between tissues and suggest that the tensile properties of composite abdominal walls are not additive. This work contributes to a deeper comprehension of these mechanical properties and will enhance patient care, refine surgical interventions and assist with more sophisticated engineering solutions.
