Elementelasticconstant(6,6,Nel) are the elastic constants of each element. The strain tensor is in the form of
Nel is the element number. These variables save the elastic constants of each elements.
For example: For wurtzite lattice
elementelasticconstant(1:6,1:6,totalelements) =0.0 do i=1,totalelements elementelasticconstant(1,1,i) = c11 elementelasticconstant(1,2,i) = c12 elementelasticconstant(1,3,i) = c13 elementelasticconstant(2,2,i) = c11 elementelasticconstant(3,3,i) = c33 elementelasticconstant(2,1,i) = c12 elementelasticconstant(2,3,i) = c13 elementelasticconstant(3,1,i) = c13 elementelasticconstant(3,2,i) = c13 elementelasticconstant(3,3,i) = c33 elementelasticconstant(4,4,i) = c44 elementelasticconstant(5,5,i) = c44 elementelasticconstant(6,6,i) = c66 ... ... ... end do
