The following stiffening peaks are even smaller than the first one. Despite felt discomfort the loads aren´t actually sky high.
Of coure this can be relative to the initial load, Tutt havign such a low load , the peaks and the discomfort level are low as well .
If the load is significantly higher at the cooldown start, maybe the thermally increased stress relaxation can´t cope with it and the initial force peak should rise.Thatś the pi you are presenting. I am not sure why?
Yet there is permanent (seemingly plastic) elongation seen with the therapeutic heat induced strain, we are nowhere near the plastic zone.
The term plastic zone, or plastic region applies with fully elastic materials. It is a engineering term fitting poorly with living biological soft tissue.
Plastic zone occurs in elastic materials under tensile stress after the elastic properties are in the end of the their range .
It can be seen in the stress strain curve as a significant flattening bonds been broken , material yielding resulting sudden significant lengthening before it breaks.
If you have been taking a look into load strain curve we are operating in the very beginning of the elastic region. A plastic zone , if there ever was one for the piece we are stretching would occur at the end of the elastic region. And we have not weakened the material that much plastic zone had been lowered this low.
That would mean we are just about to break our weapon.
Warren, Lehmann et co, have been telling since 1970 that there is relatively small amount of damages in the tissue relative the given strain with heat.
The closer the temperature was to 45C the stronger the tissue was in given strain , in fact they said that producing the strains greater we do under 45 C it can be done just about damage free.
The magic happening due thermal transition may present plastic deformation, but no way we can use the term plastic region or yield strength in this occasion.
It is a living organ having very high visco-elastic characteristics and no way the typical elastic materials stress strain curve fits in the picture.
There is one point worth noting. In my protocol, the target strain and peak load in each cycle is reached under with heat, and there is 5-8 more minutes of heated stress relaxation without any additional strain before the heat is removed. So by the time the heat is remove for a locked strain cooldown, the load has already dropped back down to 1.5kg. Then with the heat removed and the strain fixed, the penis goes through a series of autonomous stiffening/relaxing cycles, first pulsing with an positive slope to the load/time curve, and then pulsing with a negative slope to the load/time curve. At these levels, the variance of each pulse is about 0.22kg.
The lower the initial load, the lesser the cumulative load gain to the cold peak. I imagine what you are saying is correct. If I was to rapidly increase the strain to reach 5kg+ load and then immediately remove the heat, there would be a greater load climb during cooldown and it would be very uncomfortable.
Also, after the treatment today, I am increasingly convinced that the heated SR prior to removing heat and a full cooldown with fixed strain is very important. If the load is removed prior to cooldown, the collagen recoils significantly.
With regard to the plastic zone, I was surprised to see and feel the response during the treatment today. I’m increasing the strain so slowly that with modestly higher loads and more time I could’ve achieved significantly higher strains. There was no discomfort at all in the last set and the load-strain did not appear to be going parabolic. IOW, at a strain rate of 1%, the stress relaxation was still almost keeping pace with the additional strain.
