In the last three decades an interest has grown in prediction of soil stiffness. In case of dense cohesionless soils or natural overconsolidated cohesive soils the working strain to which soil stiffness is referred to covers the range 0.01-1.0%.

The formula for sand accounts also for stress level. In case of overconsolidated sandy clay, stress history, in the form of yield stress, is also accounted for.
