Abstract Data on strain energy components are reported for drained, consolidated‐undrained, and compacted tests on Yolo loam obtained by standard procedures using triaxial test equipment. The ratio of recoverable distortional to recoverable volume energy is proposed as an energy criterion for failure and as an approximation to this ratio studied. The approximation assumes that the recoverable distortional energy is a constant fraction of the distortional strain energy added to the sample by the deformation in any one test. The ratio is found to be constant, but of differing values, for the drained and consolidated‐undrained tests and to vary for compacted samples.
