He has over 40 years experience in teaching and practicing mechanical engineering design. Stressstrain characteristics of highstrength concrete. Stress is the external pressure applied to an object where as strain is the materials response to that stress. Engineering considerations of stress, strain, and strength book. It is not a handbook rather intended as a textbook for the present and hopefully future generations of strength of materials. On the stress strain curve, point e is the breaking stress point or fracture point.
