ABSTRACT = {This paper performed flexural test and numerical simulation of clay-beams 
with different water contents to study the tensile fracture of clay soil and the relevant 
mechanisms. The crack initiation and propagation process and the accompanied strain 
localization behaviors were all clearly observed and analyzed. The exponential cohesive 
zone model was proposed to simulate the crack interface behavior of the cohesivefrictional materials. The experimental results show that the bending capacity of claybeams decrease with the water content, while those of the crack mouth opening 
displacement, crack-tip strain and the strain localization range increase. The numerical 
predictions successfully reproduce the evolving tensile cracks and the strain localization
phenomenon of the clay beams with different fracture ductility, which demonstrates the 
validity of the proposed cohesive zone model in modelling clay fractures.},
