Classical LAMinate theory for the lightweight design of structures and systems in PYthon

Klassische Laminattheorie für Leichtbau-Strukturen und -Systeme in Python

Teoria classica dei laminati per la costruzione leggera di strutture e sistemi in Python

Python 3 in addition to further packages. These necessary libraries can be installed via PIP:

pip install scipy pip install numpy pip install matplotlib pip install tikzplotlib pip install pandas pip install openpyxl 

python -m pip install -U . 

You can also install CLamPy via PIP

pip install CLamPy 

See Python scripts and Jupyter notebook in test.

• Kirchhoff kinematic assumptions
  • Normals to the neutral plane remain normal after deformation
  • Normals remain straight after deformation
  • Thickness remains the same after deformation
• Ideal bonding
  • No height of bonding between plies
  • Plies cannot slip relative to each other, i.e. no shear deformation
  • The strength between plies is infinite
• Geometry
  • Constant uniform thickness
  • Thin laminate, i.e. width and length > 10 times thickness
  • Small displacements and rotations, i.e. out-of-place displacement << thickness

• Add documentation including list of all nomenclature with meaning
• Different material parameters for each ply as array
• Material library
• Plot Young's modulus of each ply
• Top and Bottom characterisctics in an array for each ply
• Set warning if material properites have strange values
• Add thermal properties
• Add moisture properties
