Orthotropic materials

Fiber glass:

  • E_{11}=35 GPa, E_{22}=10 GPa=E_{33}=10 GPa
  • G_{12}=G_{23}=G_{13}=3.5 GPa
  • \nu_{12}=0.35, \nu_{23}=\nu_{13}=0.05

Creating the mesh

GMSH

cs=60;

Point(1)={0,0,0,cs}; Point(2)={1000/3,0,100,cs}; Point(3)={2000/3,0,100,cs}; Point(4)={1000,0,0,cs};

Spline(1)={1:4};


Extrude {0, 2000, 0} {

Line{1}; Layers{20}; Recombine;
