The maximum force, stiffness and damping ratio were measured in load-displacement hysteretic curves to evaluate the multi-phased hysteretic friction behavior.
The maximum force, deformation at maximum force, strain at maximum force, stiffness, fracture energy, maximum stress at failure, fracture toughness, velocity of fracture initiation, fragility index, and velocity of crack growth as the SCB test outcomes or dependent variables (DV) were analyzed using RSM.
In our biomechanical study of MFPL reconstruction with Gracilis tendon allografts using the confluent tunnel technique, no difference in maximum tensile force, stiffness and elongation were observed between the groups.
As well known, the kinetostatic performances (repeatability, stiffness, maximum force or velocity) of serial and parallel manipulators depend strongly on the kinematic structure and on the manipulator configuration inside its working space.
Cortical thickness correlated well with stiffness, maximum force to failure and maximum energy to failure.
The spectroscopically determined PYD/divalent collagen cross-link ratio of primary mineralized trabecular bone correlated well with maximum force to failure and stiffness.
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.
The biochemically determined Pyd/divalent collagen cross-links ratio correlated with stiffness (inversely), maximum force to failure, and maximum energy to failure (inversely).
Stiffness and maximum force to failure were affected by both age and treatment, energy to failure was affected only by treatment.
The following parameters were calculated: ultimate load, Fmax (i.e. the maximum force that the specimens sustain), stiffness (the slope of the linear portion of the load-deformation curve), and work to failure (Wabs; the area under the load-deformation curve until failure).
Two measures of spinal stiffness (N/mm) were calculated: average stiffness ('AvgStiff': the slope of the force-displacement curve from10N to maximum force application; reflects tissue dynamics in response to force) and terminal stiffness ('TermStiff': average of the force/maximal displacement ratio over a one second time period when maximum force was held; reflects total bulk response)63, 66.
