Reinforcement of a quay in the Port of Le Havre with rigid inclusions (2023)

As part of the reinforcement work of the Joannes Couvert quay in the Port of Le Havre, soil reinforcement by rigid inclusions (RI) is planned to be used in the rear of the future quay structure, to allow the passage of heavy cranes during the operational phase.

Breakage modelling of clay cylinders along the feed process to a kiln (2022)

IMERYS Technology Center (IMERYS), world leader in mineral specialties for industry, called upon ITASCA France (ITASCA) to monitor and understand the mechanical evolution of cylindrical clay blocks along the feed process of their rotary kilns. The material passes from the dryer to the kiln inlet, via several conveyor belts, a bucket conveyor, successive chutes, flow pipes and a storage silo.

Simulating Spalling With a Flat-Jointed Material (2020)

Long-term storage of spent fuel is critical to the nuclear energy industry. The Swedish Nuclear Fuel and Waste Management Company (SKB) is developing an approach for the storage of spent nuclear fuel in an underground repository in competent crystalline rock. In order to better understand the spalling damage process, an in-situ test involving the drilling of two boreholes was performed in Äspö diorite at SKB’s underground hard rock laboratory in Äspö. Tests and monitoring were performed on the pillar that separated the boreholes. In order to further investigate the damage process, Itasca performed numerical modeling using PFC3D and FLAC3D.

Modeling of Spalling in PFC3D — A Quantitative Assessment (2020)

SKB is interested in developing a 3D discrete model to predict spalling on the excavation boundaries of underground repositories for the long-term storage of spent nuclear fuel. This project provided a quantitative assessment of modeling spalling using PFC3D to study both lab- and tunnel-scale behavior.
