If a two-inch specimen of the material shown were to be loaded
until it reached an overall length of 2.005 inches and then
unloaded, what would the expected length of the specimen be upon
unloading?
Homework Answers
From the diagram we can see that the strain at the final point is 0.0030 in/in in both cases.
Hence, final length= (1+strain)*initial length = (1+0.0033)*2 = 2.0066 in
After this point, breakage of specimen takes place.
