✦ Synopsis

The various factors influencing and the principal features of the deformational behavior and fracture of concrete and similar materials are discussed. The paper presents a unified theory that correlates the essential characteristics of concrete behavior under load with the phenomena of size effects on strength, stiffness and ductility. The model is based on a t~-phase material one phase being mtcrocracks. The model predicts satisfactorily the non-linear stress-strain behavior, size-dependent strength and fracture mode transition of concrete-like materials. The model also predicts a new phenomenon, the size effect on stiffness and ductility of such materials.
