Which of the following scenarios exhibits the higher stress

Which of the following scenarios exhibits the higher stress concentration factor? Assume the first case exhibits a perfectly elliptical crack, they are being pulled in uniaxial tension, and the samples are sufficiently large that the boundaries do not impact the stress state (apart from the second case being a surface crack)

Solution

A2A :))

As in the followng scenarios the case of 1st one exhibits the higer stress concentration factor probably as because the first one exhibits a perfectly elliptical crack, as by they are being pulled in uniaxial tension the vacuum present in the closed volume presently pulls the tension so effecting more and higher stress concentration as condidering the samples are sufficient large that the boundaries do not impact the stress state occured.

hope you probably understand and got the answer

all the best .thank you. :)
