Breaking the tunica??

Just out of curiosity what amount of weight would cause the tunica to snap? I have read the following “The tensile strength of the tunica is approximately 1200 – 1500 mmHg” and it made me wonder how much would be too much?

Does anybody have a rough calculation of weight required to deform tunica?

I read a force of approximately 50kg is required to rupture the tunica albuginea.

There are a couple of academic papers on the strength of the TA in this thread

The characteristics of the tunica albuginea revisited

Spoiler is there is no definitive answer. It seems to vary a lot. The first paper, in the thread, has it much lower than the second paper, in the thread. The first paper also gives reasons why the second paper is more accurate.

I guess if we know the amount of weight that would tear it then we can get an idea where the plastic deformation would take place. The key would be to figure out around what weight you would enter would plastic region of the stress strain plot. If you can stay in that region and not go beyond it to fracture point then it would only be a matter of time in that area.

Maybe somebody smart can figure that out for us.

That thread has loads on that topic. The problem is from a simple stand point you have strain, heat and time. Some combinations of those three things will give you gains. We have nothing to relate them in a manner where we can say what would work for an individual dick, it would probably end up being a non linear partial differential equation or similar.

The papers in that thread try to calculate the force needed to enter the elastic and plastic regions. The results vary wildly which adds up with what is reported here (easy gainers and hard gainers). Even still the paper posted later in the thread, which is the older paper, has the force needed to enter the elastic and plastic regions much higher than the other paper. The other paper sites that it thinks the older paper is correct and the force is much higher. If the older paper is correct then heat and time play a major part in allowing us to make gains. It’s hard to relate that scientifically.

Deformation: Intensity, Method and Recovery guidelines

Very interesting. Getting close to a answer.

”In order to deform, and then reform a ligament into a more desireable length and form, the applied “constant” load must reach over 40% of that particular ligament’s “ultimate load”. A ligament’s ultimate load is defined as “the final load reached by a structure before failure”.”

This is supposedly ideal force so that the fibers don’t revert to their original state but rather remain elongated. (No word on whether heat changes this threshold though.) Now, we don’t know the ultimate load of the tunica and/or ligaments but considering lig pops and other phenomena I’d say that manual stretching, if fairly intense, should at least approach that 40% cut-off.

The 40-45 LB zone is starting to make sense. This then brings two questions to mind. How much less weight would be required if we apply heat? How much time at that high weight? I notice that steel takes 5-8 minutes at the fracture weight to fail.

This video is making me feel that something along the following lines might work. (Thanks to Xeno, MX and Shiver for their ideas on the application of the Inflammatory Proliferative Remodeling (IPR) Scale on hanging)

A routine could be the following;

A-Heat Penis to 104-113F range for 5-10 minutes
B-Start hanging and slowly increase weight until you get to the 40-45 LB range. (try to work to 5 minutes in that range) all the while apply heat for the first 10-15 minutes.
C-Remove hanger and edge for 10 minutes.
D-Rest for 2 days.
E- Repeat this cycle for 4 to 8 weeks
F- Decon (Nothing) for at least 3 weeks to 3 months.

I keep using this thread as a reservoir of information.

How much strain can a ligament withstand before tearing?

Tendons and ligaments can be strained to between 5% and 7% without damage. The maximum strain that a ligament or tendon can endure before failure is generally in the neighborhood of 12% to 15%; however, substantial damage to the collagen network can occur well before complete rupture. (comes from below link)

The following link also shows that 4-8% strain on college fibers.

Don’t forget the edging part! Ha

Game changer study may 2022

This study just came out a month ago.

MP38-10 TENSILE STRENGTH OF PENILE TUNICA ALBUGINEA IN A HUMAN MODEL | Journal of Urology
PDF

https://www.aua journals.org/do … 000000002592.10

I believe that if we have the ultimate tensile strength we can now calculate the elastic and plastic regions.

Just wanted to share a little of what I am working on.

I am obsessed with finding the entry to the plastic region so no apologies.

I figure with the above information and the use of the load calculator one can get a very good idea.

I am currently using 125 mm as girth and we have a UTS of 1.7 Mpa for human TA.

That gives me UTS of 75 LB

40% ot UTS = 30 LB
50% of UTS = 37.5 LB
60 % of UTS = 45 LB

If we use heat we can lower that by 25%

40% with heat = 22.5 LB
50% with heat = 28.125 LB
60% with heat = 33.75 LB

I figured 25% decrease with heat off this article.

Effect of heat and cold on tendon flexibility and force to flex the human knee

So what I am looking for is to add in a 3-5 minute set every couple days at a weight that enters the plastic region. Just enough to cause damage but not rupture the TA.

Good reference thread. How is that going for ya? What weight % you would attempt?

Why would you want to stretch higher than 0.17 Mpa?? What are you trying to achieve here?

This has been disccused by manko, kyrpa and tutt in the past, there is no need to go to higher loads, there is no benefit, unless you want to move a car with your penis. But since everyone decided to follow the thermal pad + hang trend (without accurate readings + measurements), good luck doing 6-9 months decons while hanging 15kg at a time.

I am still gonna follow kyrpa/igigi threads that use ultrasound and moderate weights. Anyways good luck in your journey and so on
