Question
Develop a function-m file in MATLAB that can be used to generate stress-strain curves for
normal and high strength concrete under uniaxial compression by programming the incremental
constitutive equations (Eqn. 48 and Eqn. 49). Eqn. 48 is strain controlled, whereas Eqn. 49 is
stress controlled.
Main input parameters are fc', Eo and Poisson’s ratio ν. Output shall be plots of stress-strain
curves.
