Question
QUESTION 2 (a) Stress and strain diagram of 316L stainless steel is plotted in Figure Q2 (a). Determine and label the following terms: (i) Proportional limit point (0,ɛ) (ii) Yield point (0,ɛ) (iii) Ultimate point (0,8) (iv) Fracture point (0,8) (iv) Modulus of elasticity or Young's modulus (E) 700 400 600 500 300 400 200 6 300 200 E 100 100 0.005 0.01 0.015 0.02 0.05 0.1 0.15 0.2 0.25 0.3 0.35 0.4 0.45 Strain, E (mm/mm) Strain, E (mm/mm) Figure Q2 (a) (b) A short post AB constructed from a hollow circular tube of aluminium, supports a compressive load of 116 kN as in Figure Q2 (b). The inner and outer diameters of the tube are di=100 mm and dz=112 mm, respectively, and its length is 400 mm. The shortening of the post due to the load is measured as 0.3 mm. Determine the compressive stress and strain in the post. Note: the weight of the post is neglected. 116 KN A 400 mm Figure Q2 (b) Stress, o (MPa) Stress, a (MPa)
