On Some Global Identification Problems in Rheology of Solids
As it’s known, the most parametric identification techniques in Rheology of Solids are based on experiments with specimens as bars, rods, tubes and beams by using a very simplified formulation of the corresponding inverse problem. The resulting stress field is homogeneous and it don’t verify all boundary conditions, only globally. To reproduce in laboratory a quasi-homogeneous stress field, geometrical restrictions on specimens must be imposed but which can’t be accomplished for heterogeneous materials like soils rocks, composites.
