LUSAS Academic 23.0: Educational Finite Element Analysis Software
LUSAS Academic 23.0 is the educational version of LUSAS’ professional FEA software, providing teaching and research access to advanced structural and geotechnical analysis capabilities. Version 23.0 is a major release (October 2025, with updates 23.0-1 and 23.0-2) featuring pushover analysis, fibre-reinforced concrete modeling, new geotechnical soil models, and enhanced scripting tools .
Key New Features in Version 23.0
Pushover Analysis & Plastic Hinges
-
Pushover Curve: New facility extracts pushover curve; derives “performance point”/“target displacement” per design code
-
Plastic Hinge Enhancements: Supports interacting/non-interacting hinges; auto force-displacement for steel sections; inspect specific hinge responses
-
Hinge Status Visualization: Plot contours for Immediate Occupancy, Life Safety, Collapse Prevention categories
Concrete & Material Modeling
-
Fibre Multi-Crack Concrete: Plastic-damage-contact model with damage plane formation; combine with creep/shrinkage codes
-
Surface Reinforcement Zones: Define bar size, spacing, cover, skew; Cartesian/radial layouts; visualize reinforcement extents
