Given your understanding of what initiates and controls failure in materials, which of the following will increase the failure strength or lifetime of a test piece or component and why? a. Polishing to reduce surface defects b. Decreasing the temperature below the brittle-ductile transition temperature, to make it harder c. Increasing its volume, to give a larger cross sectional area Od. Increasing the grain size so there are less grain boundaries to initiate failure Oe. Decreasing the difference between the maximum and minimum stress values, as this effects the stress concentration factor

QUESTION 15 A company that supplies materials undertakes a polish before delivery. This removes any scratch greater than 1mm from the surface. If you require a plate 1 92 cm wide made from an Aluminium alloy (7075), with K1c-24 5 MPa m0.5, what is the maximum stress the material can undergo before catastrophic brittle failure would occur? Give you answer in MPa, to 3 significant figures and do not include the units in your answer
Experience in non-destructive testing of 7075-T651 aluminum (Sy = 72 ksi, KIC = 22 ksi in1/2) pressurized pipes dictates that the minimum detectable longitudinal crack length is 10 mm. Thus, a longitudinal crack of length 10 mm could escape detection and be present at any time. The pipes transmit a flow of natural gas and the presence of a crack would not alter the internal pressure. What maximum internal pressure would you recommend? Neglect the pipe curvaturewhen determining the stress intensity factor.
