Three stages of stress-strain response in flexure. (a) Stage I: elastic behaviour in compression and tension. (b) Stage II: elastic behaviour in compression and plastic behaviour in tension (cracking stage). (c) Stage III: nonlinear behaviour in compression and plastic behaviour in tension (ultimate stage).
