Typical curve of compressive force versus fracture gap (stress-strain curve) from specimen H1141 (right side). We defined the point of clinical failure as 2 mm of fracture gap. We defined the point of mechanical failure as a point at the end of the linear part of the curve. We defined the stiffness as a slope of linear regression among all points up to the failure point.
