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), with the shear correction already applied, by default with the equilibrium approach of Rohwer (1988); also available: Vlachoutsis (1992), Whitney (1973), Chow (1971), Birman and Bert (2002), the thickness-shear frequency of Yang, Norris and Stavsky (1966), and a constant 5/6
- E, F, H for third-order shear deformation theory (TSDT)
-
Transverse shear stresses through the thickness, from the shear forces or recovered a posteriori from the strain gradients of an FSDT solution (Noor and Peters, 1989), with the corresponding transverse shear strain energies
-
Material invariants, trace-normalized or not
-
Lamination parameters based on material invariants
-
Stiffness matrices (ABD) based on lamination parameters

History
- version 0.1.0, from sub-module of compmech 0.7.2
- version 0.2.2, from sub-module of meshless 0.1.19
- version 0.2.3 onwards: independent of previous packages
- version 0.3.0 onwards: with fast Cython version, not compatible with previous versions
- version 0.4.0 onwards: fast Cython and cimportable by other packages, full compatibility with finite element mass matrices of plates and shells, supporting laminated plates with materials of different densities
- version 0.5.4 onwards: verified lamination parameters, analytical gradients of Aij, Bij, Dij with respect to lamination parameters, supportting MAC-OS
- version 0.5.17 onwards: installing with pip
- version 0.6.0 onwards: cibuildwheel to distribute for Linux
- version 0.7.0 onwards: added Kassapoglou's module
- version 0.8.0 onwards: support for Third-order Shear Deformation Theory (TSDT)
- version 0.9.1 onwards: A44, A45, A55 with the shear correction already applied (Rohwer, 1988), transverse shear stress recovery, picklable Laminate and GradABD, improved Cython and compiler flags (0.9.2), see CHANGELOG.md
- version 0.9.12 onwards: shear correction methods of Whitney (1973), Chow (1971), Birman and Bert (2002) and Yang, Norris and Stavsky (1966), a posteriori transverse shear stresses and energies (Noor and Peters, 1989), Atrans, Dtrans and Ftrans deprecated in favour of Ats, Dts and Fts, see CHANGELOG.md
