The increasing threat of blast loads on critical underground infrastructure has necessitated advanced protective measures for tunnels. Ultra-High Performance Concrete (UHPC) has emerged as an excellent material for blast-resistant structures due to its superior strength and energy absorption capacity. When combined with Glass Fiber-Reinforced Polymer (GFRP) protection, UHPC tunnels can ...

In Abaqus, CEL (Coupled Eulerian-Lagrangian) and Eulerian analysis are advanced techniques used to model complex problems involving large deformations, fluid-structure interactions, and multiphase flows. These methods are particularly useful when traditional Lagrangian approaches struggle to handle severe mesh distortions or when fluid behavior dominates the problem Eulerian Analysis Eulerian analysis is a framework where ...
