A_2 Question 5 (10 marks) H= 5 The uniaxial stress-strain constitutive behaviour of concrete can be described by the following nonlinear relation o= E(E) where is the strain and E() is the modulus defined as E E(E) = 1+ in which E; = 30 + A + H GPa and Ep = 0.01. Evaluate the strain e when a stress o = 0.1 GPa by means of Newton-Raphson or secant method. Consider a tolerance relative error of 0.001.
