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… More >
