PSIRail3D™

Railway Infrastructure Modeling

PSIRail3D™ is a 3D finite element model used to predict performance and assessment of railway infrastructure. PSIRail3D™ incorporates a variety of material models for both soils and aggregates, including viscoelasticity, plasticity and nonlinear and linear elasticity. Deflections, stresses and strains responses on the structure are outputs of the model, allowing users to minimize stress concentrations and limit deflections above certain criteria.
