The table and graph below display the experimental results of a load-deflection test of a beam manufactured using steel fibre concrete (SFRC). The test objective was to assess the flexural characteristics of tested SFRC. Load (kN) Mid span deflection (mm) P/2 P/2 2,6 3,5 0,08 0,11 0,15 L/3 L/3 L/3 4,5 0,25 L = 450 mm, b = h = 150 mm 7. 5,7 0,309 0,34 0,4 6. 5,5 5 4 0,48 4 0,62 4 0,67 0,88 4 4 1,32 2 3,8 2 3,6 3,6 3,5 2,84 3,88 4,4 4,9 2 4 3,5 3,2 Mid-span deflection (mm) 6 Your task includes developing program commands to: B1: Produce a 2D plot for the load-deflection relationship. (3) B2: Use two numerical integration methods to determine the energy absorbed by the tested beam (i.e. area under the curve). (5) B3: Provide a comment on your findings relating to B2 above.
