... at small stress. The branch of soil mechanics studying these relations is critical state soil mechanics. It may be interesting to mention that during cyclic loads soils usually tend to contract ... normal force can only be a compres- sive force. Tension can not be transmitted, unless the soil particles are glued together. Such soils do exist (e.g. calcareous soils near the coast of...
