Probably I wasn'n clear enough. I do not mean the stresses in the PU itself, but the stresses in the adhesion. Yes, I can make them in Vee, but it does not help a lot since I have an objective to maximixe the lifetime and minimize the costs and dimensions.
Thank you SacovanLoon !
Well, according to our PU coating supplier, they advise the deformation not higher than 20% of original thickness.
Indeed, the adhesion strength (shear stress at the interface) is driving in this case.
Now I am trying to evaluate the allowed shear stresses based on the...
Thank you Nick for your answer.
Well, let say our manufacturer can reach a certain degree of adhesion and even further they can assure us that the interface stength is stronger than the liner itself, what design criteria could you suggest for the liner?
Would it be max. stretch or max. stress...
Hallo everybody!
I have a task to calculate the thickness of the polyurethane or rubber coating to be applied to the steel core of a roll. The roll to be used to transport heavy pipes. The polyureathane liner will be casted over the steel body.
Could anyone suggest me what design criteria...
