dc.descriptionAbstract: Personnel of the Geotechnical and Structures Laboratory, U.S. Army Engineer Research and Development Center, conducted a laboratory investigation to characterize the strength and constitutive property behavior of adobe. A total of 46 mechanical property tests were successfully completed: two hydrostatic compression tests, four unconfined compression (UC) tests, eighteen triaxial compression (TXC) tests, five direct pull (DP) tests, six reduced triaxial extension (RTE) tests, two uniaxial strain tests, four uniaxial strain load/biaxial strain unload tests, and five uniaxial strain load/constant volume (UX/CV) tests. In addition to the mechanical property tests, nondestructive pulse-velocity measurements were performed on each specimen. The TXC tests exhibited a continuous increase in maximum principal stress difference with increasing confining stress. A compression failure surface was developed from the TXC test results at nine levels of confming stress and from the results of the UC tests. The results for the DP and RTE tests were used to develop the extension failure surface. The resulting compression and extension failure surfaces were well defined and nonsymmetric about the mean normal stress axis. Good correlations were observed between the stress paths obtained from the UX/CV strain path tests and the failure surface developed from the UC and TXC tests.-
