Unconfined compressive strength cohesion

Web30 Oct 2008 · If you perform an unconfined compressive strength test you will get a maximum deviator stress for some failure criterion. That maximum deviator stress is the diameter of a Mohr's circle. So half of that value is some measure of shear strength for … Web16 Aug 2024 · Scope. 1.1 This test method covers the determination of the unconfined compressive strength of cohesive soil in the undisturbed, remolded, or compacted condition, using strain-controlled application of the axial load. 1.2 This test method provides an approximate value of the strength of cohesive soils in terms of total stresses.
