Advanced Elements and Material Models

LUSAS high-performance element libraries include:

• Plate and shell elements for slabs and walls
• Beams and shells for prestressed, steel and composite construction
• Cable elements for cable stay and suspension structures
• Solid elements for local effects
• Generalised joints / springs

Additional element information is given on the product specification page

Linear Materials include:

• Isotropic, orthotropic, anisotropic and rigidity models
• Isotropic and orthotropic thermal material models
• Composite lay-ups for shell and solid materials

Nonlinear Materials include:

• Plasticity model with isotropic and kinematic hardening using von Mises criteria.
• Anisotropic plasticity model with isotropic hardening using Hill or Hoffman criteria.
• Plasticity model with isotropic hardening using a modified von Mises criteria with different properties in tension and compression.
• Geotechnical model using Mohr Coulomb criteria including non-associative flow for soils and rocks
• Volumetric deformation soil model
• Viscoelasticity
• Two Phase change material
• Concrete models with opening and closing of cracks, concrete crushing, and strain softening based on fracture energy in 2D/3D
• Creep models with time dependency and strain hardening
• User material model interface

All linear and nonlinear materials include temperature dependency
