Abstract
In the international literature there is often a confusion between the terms
Modulus of Elasticity, EYoung, and Modulus of Deformation, EDef which is sometimes
plainly referred to as Modulus E. In this paper the definitions of both the EYoung and the
EDef have been clarified. Moreover, a soil classification diagram has been derived based
on numerical analysis through a finite element software where soils are classified
according to their shear strength parameters (c, φ) and their behavior under loads
generated using a rigid circular bearing plate. Finally, a method for the determination of
shear strength parameters, as well as the EYoung of soils has been proposed using the insitu
Plate Bearing Test and solving a 3x3 mathematical system. The study and
documentation of the proposed method is supported through three theoretical examples.
