A 200mm long, 10mm dia. tensile sample experienced plastic deformation at a strain of 0.01. The applied load was 78.5 kN.
• What is the elastic modulus of the material?
• By how many mm did sample elastically deform?
Looking at the Ni-Cu phase diagram answer the following questions.
• At what temperature is a Cu (20%) - NI(80%) fully solid?
• What phases are present at 1300°C and 50%Cu50%Ni?
Draw and label an engineering stress-strain diagram for a brittle metal.
