Software Specification

Note that because advanced elements are required for this type of analysis LUSAS Composite is only available as a 'Plus' version.

LUSAS Composite plus

A feature-rich engineering analysis system for advanced composite analysis consisting of:

  • Extended advanced high-performance element library including:
  • Bars
  • Thick + thin beams
  • Plane stress/strain continuum
  • Axisymmetric solid continuum
  • Solid continuum (high order)
  • Flat thin membranes
  • Curved thin semiloof shells
  • Curved thick shells
  • Axisymmetric membranes
  • Axisymmetric thin shells
  • Axisymmetric solid continuum with non-axisymmetric loading
  • Generalised joint/springs/gaps.
  • Advanced materials including:
  • Isotropic, orthotropic, anisotropic and rigidity models, composite lay-ups for shells and solids, temperature dependency.

For: Linear static stress, linear buckling, natural frequency, fatigue, nonlinear and dynamic analysis problems when used with the appropriate LUSAS Composite plus option.
