This paper reports on use of singular fractal functions to generate constitutive laws of quasi-brittle materials like concrete. Singular Fractal Functions belong to a class of monotonically Increasing functions which are differentiable almost everywhere, possessing zero derivative, throughout their domain. Fracture surfaces of quasi-brittle materials like concrete and also crack pattern are considered as irregular objects called as natural fractals. The results of simulations obtained in the present study are compared with existing experimental results and it is encouraging to use that the results match closely.
