The threshold strain
Webclass. For rock mass failure, a strain rate of less than 0.1% was recorded with an upper bound value of 3%. It is suggested that 4% may be a reasonable maximum strain threshold for non-kinematic failure in the poor to fair rock mass quality classes.

When the threshold of initial damage of limestone is less than 0.18, the compressive strength of the limestone is found to meet the engineering requirements.
WebFeb 19, 2024 · This strain energy measured at each increment of the strain is compared with a threshold value characteristic of each material, threshold value beyond which the material breaks. This approach has been shown to be effective for the description of creep failure in that it allows a failure criterion to be defined. WebThreshold shear strain for cyclic pore-water pressure, γ t, is a fundamental property of fully saturated soils subjected to undrained cyclic loading.At cyclic shear strain amplitude, γ c, larger than γ t residual cyclic pore-water pressure changes rapidly with the number of cycles, N, while at γ c < γ t such changes are negligible even at large N.To augment limited …
