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.

• Integrated Windows User Interface
• Integrated DXF and IGES interfaces
• Fast Iterative Solver Technology

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