The aim of the project is to develop new numerical tools for modelling large deformation problems in geotechnics. This effort is expected to lead to new commercial codes, resulting eventually in a major improvement in geotechnical R&D and innovation in foundation methods. The core of the proposed project is to validate and demonstrate the new methods and tools, which involves real field applications, through intense collaboration between industry and academia.
The main scientific and technological objectives of the project can be summarised:
-
To enhance quasi-static and dynamic MPM codes by implementing time-dependent hydro-mechanical coupling to enable coupled analyses in the presence of fluids for quasi-static loading.
-
To enhance the accuracy of the MPM codes by implementing high-order tetrahedral elements. This is necessary for obtaining accurate results with non-linear soil models.
-
To develop and implement interface elements, membranes and structural elements for the MPM codes to enable accurate modelling of soil-structure interaction problems.
-
To improve the computational speed of the dynamic MPM code via parallel computing to enable the use of the code for complex 3D applications.
-
To expand the library of constitutive models available in the MPM code to enable appropriate modelling of the complex rate-dependent behaviour of soft natural soils, stiff clays and sands/granular materials.
-
To develop a suite of simplified benchmark problems involving installation of geotechnical structures for analyses with the MPM and finite element codes.
-
To validate and demonstrate the computational methodologies developed during the project for modelling installation effects of piling, ground improvement and special applications, including offshore foundations.
-
To translate the results obtained by experimental research, FEM and MPM analyses on installation effects to further develop the embedded pile concept and volume averaging technique used in the extended FEM for day-to-day geotechnical engineering applications.
-
To train geotechnical engineers and scientists in advanced soil modelling and numerical analysis with MPM and FEM.
-
To disseminate the results, as openly and transparently as possible, to scientists and geotechnical professionals via publications and annual workshops.
