| Summary: | The inclusion of a geogrid, in the angular aggregate, results in the development of a new composite layer, the modulus of which is higher than the unreinforced material. That results from the gradual stiffening process of multi-layer structure by the function of interlocking when subject to repetitive loading. The analysis of this process is tackled in the framework of sensitivity theory allowing for the development of a composite layer around the geogrid. The modified elastic continuum theory was utilized to develop the constitutive model. The concept of permanent modulus of deformation was incorporated. The analysis process required the deformed geometry updating. The theoretical formulation of sensitivity analysis employed the adjoint method. It allowed for determination of the permanent modulus of composite layer that was much higher as compared with unreinforced system. |
