N2 - An understanding of failure mechanisms in softbiological tissue is vital in medical issues such as ruptureof foetal membranes and injuries to skin, muscle, andtendon during sporting activities. Fracture toughnessdetermination in soft collagenous tissues (SCT) is oftenmodelled as an interchange between the work done toovercome internal strain energy of the tissue (viscousenergy) and the irreversible work done to propagate adefect (fracture energy). Conventionally, the viscousenergy is determined on unnotched samplesexperimentally and after notching the fracture toughnesscan be calculated, based on the increase in dissipatedenergy. We hypothesized that the adaptive quasi-linearviscoelastic (AQLV) model [1] is able to predict theviscous energy of unnotched samples properly andhence, enable reasonable fracture toughnessdetermination by modeling.
