Abstract
Further development and implementation into numerical program of a developed model for Hard Soils and Soft Rocks S_BRICK (Vukadin & Jovičić & Likar, 2004,2005) represents the main goal of the applied research project. The S_BRICK model was already validated on a conceptual level where the results showed that S_BRICK was able to capture stress-strain behavior typical for structured material in accordance with theoretical framework proposed by Cotecchia & Chandler (2000). In the proposed project S_BRICK model will have to be validated on the laboratory data from Hard Soils and Soft Rocks with different types of structure and destructuring. This will potentially lead to a further improvement of the formulation of a model. The validation will be followed with implementation of a S_BRICKS into numerical program that has a commercial and technical value. The selection of an appropriate numerical program and implementation represents second phase of a proposed project. The final phase of the project will be the validation of a S_BRICK on a different geotechnical boundary problems. Transferring the basic knowledge on mechanical behavior of Hard Soils and Soft Rocks into application will be the final result of the proposed project. This could in turn lead to more efficient, safe and economical designs for geotechnical objects designed in those materials.
