Fracture mechanics of cement mortar and plain concrete
AbstractThe classical Griffith theory is modified to include the prepeak non-linear and postpeak tension-softening response of cement mortar and concrete. This is done through the notion of an equivalent (effective) brittle material which permits the calculation of the real fracture energy GF of the material. The latter is used to explain the ductile-brittle transition via the (energy) brittleness number. A simplified procedure for studying the crack growth in cement mortar and plain concrete is formulated on the basis of an equivalent elastic material, and its limitations are pointed out.
