The model explains the change of craze stress-extension relation and also the difference of fracture-surface roughness.
We first show that the classical gas-like theory of rubber elasticity is incorrect because the force-extension relation for an individual polymer chain is dependent on the interaction of its chain segments with segments of other chains in its neighbourhood.
Ankle torque production also depends on the joint position or angle (the torque-angle relation; Tθ), the joint angular velocity (the torque-angular velocity relation; Tω), and the series elasticity (the torque-extension relation; TΔL) of the muscles crossing the joint.
For some biological materials, like fibrin protofibril gels or crosslinked F-actin where the polymer persistence length is on the order of the distance between crosslinks, nonlinear elasticity is thought to result from the intrinsically non-linear force-extension relations of the network strands [11].
A plot of the crack extension in relation to the CTOD is plotted in Fig. 10.
The only information which is not directly measured in the borehole is the crack extension in relation to the reference volume.
As we reconsider Extension in relation to the centennial in May of 2014 of the Smith Lever Act, which established the national Cooperative Extension System, it would serve us well to remember these words from C.B. Smith and Ruby Green Smith (they weren't related, by the way).
Although male physiotherapists may differ in their views to some extent, it is unlikely that their perceptions about role extension in relation to sickness certification would dramatically deviate from female physiotherapists.
The initial aims of the research were not to investigate 'boundary work' but to explore different views towards role extension in relation to the sickness certification role by three groups of healthcare professionals.
