摘要
Soil briquets from a Vertisol and two Oxisols, equilibrated over a range of 15 to 936 bar water tension were subjected to a constant rate of strain. The trend in measured flexure and stress at rupture was adequately predicted by theory, but the measured values differed from calculated values by a large factor. The breaking stress or modulus of rupture followed the same trend as the ratio of the material's surface tension to a parameter which measures pre-existing, microcracks. Elastic constants were necessary, but not sufficient to accurately predict cracking.
