Compute the magnitudes of the normal stresses

Reference no: EM13561448

The parameter K in Equations 9.7a, 9.7b, and 9.7c is a function of the applied nominal stress (sigma) and crack length (a) as K=sigma(sqrt(pi*a).

Compute the magnitudes of the normal stresses (sigma,x) and (sigma,y) in front of a surface crack of length 2.0 mm in response to a nominal tensile stress of 100 MPa at the following positions:

a) r= 0.1mm, theta= 0?

b) r= 0.1mm, theta= 45?

c) r= 0.5mm, theta= 0?

d) r= 0.5mm, theta= 45?
