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.
LUSAS Composite plus Options
