HERCULES brings together a multidisciplinary team to develop further our understanding of geohazards making infrastructure more resilient under changing climates. The programme will undertake fundamental research to assess and predict risks due to geohazards ultimately helping inform end-user delivery. The proposed study will employ a range of novel research approaches across multiple scales, from the macro-scale, e.g. by integrating Earth Observation techniques, through the meso-scale, e.g. by running experiments in the laboratory, to the micro-scale e.g. by investigating the ground behaviour at the scale of soil particles experimentally using tomography and develop numerical techniques as the Discrete Element Method.

A hypoplastic constitutive model for the time dependent behavior of soils will be developed. The model parameters will be determined with the help of own laboratory tests and test results from literature. The constitutive model will be implemented in a Finite Element code. The numerical model will be used to study the creep failure of soil slopes. We will carry out centrifuge model tests to study the failure mechanisms of creeping slopes. Moreover, the numerical results will be compared with the centrifuge model tests.

Fracture of materials is problematic across many disciplines and scales, from large building collapses and costly preventative engineering fixes to the personal injuries caused by bone fracture. 80–90% of all structural failures occur as a result of fatigue and thus fracture mechanisms. Extensive testing of materials for fracture parameters before use in specific applications can be costly, wasteful and prohibitive when creating large structures. Computer models can be used to assess the probability and impact of fracture for a specific application and material, thus serving as a prediction tool. However, the models used are not accurate and reliable across multiple scales and across varying applications. Fracture across Scales and Materials, Processes and Disciplines (FRAMED) aims to develop a predictive modeling framework for fracture which will be applicable across multiple scales and materials, and across multiple disciplines and processes; the target audience for applications are designers in the engineering field. FRAMED will utilise the Marie Skłodowska-Curie Research and Innovation Staff Exchange (MSCA-RISE) scheme to create a multi-disciplinary consortium consisting of engineers, chemists, material scientists, physicists and applied mathematicians to create accurate and robust fracture models that can be used across a variety of scales, materials, processes and disciplines. We will enhance the research and development work to be undertaken, providing a solid foundation for long term international and inter-sectoral collaboration. High quality research and development work will be carried out via international and intersectoral secondments, facilitating the creation of professional networks and knowledge transfer.
