The effect of the specimen length on the tensile strength and on the stability of the fracture process in direct tension is investigated. Tests have been carried out on cylindrical specimens with a constant cross section but with different length. It was found that the tensile strength decreases with increasing specimen length. The influence of the strain softening behaviour on the stability of fracture is discussed.
