Methods for analysis and design of composites

High-performance module to calculate properties of laminated composite materials. Usually, this module is used to calculate:

• A, B, D, E, F, H plane-stress stiffness matrices

  • A, B, D, for classical plate theory (CLT, or CLPT)
  • A44, A45, A55 for first-order shear deformation theory (FSDT)
  • E, F, H for third-order shear deformation theory (TSDT)

• Material invariants, trace-normalized or not

• Lamination parameters based on material invariants

• Stiffness matrices (ABD) based on lamination parameters
