You are given a 10-cm-diameter cylindrically shaped extruded bar (length = 50 cm) of an aluminum alloy. a. What specimen configurations would you use to characterize the degree of anisotropy of the material’s fracture toughness? b. If the lowest fracture toughness of the bar was found to be 20 MPa √m , what would be the load level needed to achieve this stress intensity level? c. Confirm the presence of plane-strain conditions, given that σys = 500 MPa. (Assume specimen thickness = 1 cm, a/W = 0.5, and bar diameter = 1.2 W.)

Question
You are given a 10-cm-diameter cylindrically shaped
extruded bar (length = 50 cm) of an aluminum alloy.
a. What specimen configurations would you use to
characterize the degree of anisotropy of the material’s fracture toughness?
b. If the lowest fracture toughness of the bar was
found to be 20 MPa √m , what would be the load
level needed to achieve this stress intensity level?
c. Confirm the presence of plane-strain conditions,
given that σys = 500 MPa. (Assume specimen
thickness = 1 cm, a/W = 0.5, and bar
diameter = 1.2 W.)
