Besides the fact your numbers are complete bullshit and any retard can make that stuff up....

That is NOT how you calculate fatigue.

One last note, we're going to ship a manifold that weighs 240,000 lbs. Again, the roads have to be built to withstand that. Yet, I don't see cars out there driving around weighing anything near that.

No, those numbers aren't complete bullshit you fucking moron. Look it up. And if you're shipping a manifold that weighs 240,000-lbs I gauren-damn-tee you you have to have a special permit for that as well as pilot cars and the whole getup.

I'm sure you know all about shit like this sitting in your comfy downtown Houston office

Do you know anything about Cameron?.... And yes, your numbers are bullshit and that's not how you calculate fatigue. I'm glad you're not above stooping to educational dishonesty to try to win an argument.

For those of you who don't know how to calculate fatigue, I give you exhibit 1:



This is a fatigue curve, or stress vs cycles. The way this works, is that each time you cyclically stress something, by applying a load, the material's strength is reduced. As a material's strength is reduced, it takes less stress to make that material yield/plastically deform/fail. In this curve, Al can handle a load of 320 MPa before failure. However, if you apply less than that, Al will not fail. However, it's strength will be reduced so that next time, you might apply less than 320 MPa but it will still fail. Equipment can be designed to never fail. For instance, if I apply only 50 MPa to this specimen, it will have infinite life. No matter how many times I apply that load, it will never fail. Any time I apply a load above it's infinite life threshold, which in this graph appears to be around 80 MPa, it makes the curve more steep which means I have permanently fatigued the specimen. The more stress you apply to a material, the more you fatigue it, thus permanently weakening its ability to resist yielding.

To make a long story short, a car applying it's load to a road designed to handle a 250K lbs of load will not fatigue the road anywhere near a truck with a 140,000 lb equipment loaded on it will reduce the strength of that road. Roads would need very little repair if it were not for trucks.

So in order for Dogmeat to calculate the "Damage factors" he would have to know the yield strength and ultimate strength of the road, which he does not. And thus, everything he did means absolutely jack shit. So please do not buy into his nonsense. His math says nothing, other than he makes up numbers to confuse you into thinking he knows something.

Welp, I'll thank you for giving me a review of an S-N curve. And you are correct.

So ... do you happen to know what the S-N curve for a composite material looks like?
