# 1 The fracture properties of steel and aluminum are: steel: aluminum: KIC = 80 MPam, KIC = 30 MPam, OY y = 800 MPa = 300 MPa [36.63] Compare the plastic zone size for the two materials' plane stress Mode I fracture at failure. Sketch what you imagine the crack tip area (the crack tip deflection) to look like just before failure. # 1 The fracture properties of steel and aluminum are: steel: aluminum: KIC = 80 MPam, KIC = 30 MPam, OY y = 800 MPa = 300 MPa [36.63] Compare the plastic zone size for the two materials' plane stress Mode I fracture at failure.
