Patient discussion about tearing

Q. Is ligament heating better than an arthroscopic surgery? I have a partial tear in my left knee (acl) and they wanna operate on me. I heard heating it can solve the problem. is it true?

A. i never heard of "ligament heating" from what i know- ligament has limited ability to regenerate. if partially torn it may need only physiotherapy and care. but if it's torn more then it can heal by itself- you need surgery. this is why there's orthopedics- to evaluate the situation, give you a diagnosis and the recommended treatment. it's always good to second guess because they are only human. you can ask other orthopedics and see what they say.

It is evident that this model predicts that material becomes very intolerable to imposed strain rate and very susceptible to hot tearing as the temperature approaches solidus.
Experiments were performed up to around 707F (375C) for this alloy, and no hot tearing was reported.
The underlying hypothesis is that hot tearing may be avoided if thermal expansion and shrinkage of the mold and casting occur simultaneously.
2, this result does not give a conclusive proof of hot tearing. The ratio is positive, meaning both casting and mold shrink at these points when the casting is around solidus temperature.
Therefore, according to the simulation, mold expands while castings shrink when the fraction of the solid phase is around 0.75, when the danger of hot tearing is not so great.
So, the simulation would show no danger of hot tearing if this result was used as a prediction.
Figure 4 shows the tearing energy of the CSM tubes taken from the same hoses that the covers were taken from for figure 3 along with some additional hoses, for which the covers were not available.
Power steering hoses removed from high mileage vehicles also show a decrease in their tearing energy as compared to unaged materials.
Thus, the results predicted by the oxidative aging model appear to work well for modeling the decrease in the tearing energy of power steering hose covers from high mileage vehicles.
From table 2 we know that the decrease in tearing energy for tubes removed from high mileage vehicles appears to be significantly less than that done by impulse testing.
The biggest roadblock to using the results of this study to predict the life for hoses is the lack of knowledge of the minimum tearing energy required to prevent a hose from undergoing significant amounts of crack growth.
Thus the only practical way to estimate the minimum tearing energy necessary for a hose to be functional is to examine hoses removed from high mileage vehicles.
