DOI: 10.1007/s10706-017-0163-6
Abstract: Cracks initiate and propagate when tensile stress, caused by an increase in suction, becomes greater than tensile strength in expansive soils. It is important to understand the variation of tensile stress with suction for properly… read more here.

DOI: 10.1007/s40093-019-0265-7
Abstract: PurposeThe swelling characteristics and cracking of expansive clayey soils usually lead to their low yield, and as a result, large areas of expansive soils remain uncultivated and unproductive. There is a need for the development… read more here.
