Contralateral unoperated tendons were failed in uniaxial tension to determine maximum or failure force, from which safety factor (ratio of maximum force to peak in vivo force) was calculated for each activity.
The maximum bending load at rupture was considered as the failure force.
Failure force was defined as the maximum force attained, while failure elongation was the elongation at the failure force.
Rotor blade failure forced down one helicopter.
Cortical thickness correlated well with stiffness, maximum force to failure and maximum energy to failure.
The biochemically determined Pyd/divalent collagen cross-links ratio correlated with stiffness (inversely), maximum force to failure, and maximum energy to failure (inversely).
Maximum force to failure correlates well with biochemically, and spectroscopically determined trabecular pyd/divalent collagen cross-links, TriSmi, Tb.Th, and Ct.Th.
Compression mechanical tests indicated differences among the various animal groups in bone stiffness, maximum force to failure, and energy to failure, the first two being affected by both animal age and treatment, while the third only by treatment.
In addition, the absorbed energy increased with increasing exposure temperature, while the maximum impact force and compressive failure load after impact decreased with increasing exposure temperature due to the degradation of the matrix properties and fiber matrix interface properties at higher temperatures.
Decreased failure stress of healing ligaments was detected, even though one OVH No scar MCL triggered the load cell safety limit before complete failure and the maximum recorded force was used as a conservative estimate (Fig. 6).
