HELIUS2_ELASTIC can be called to obtain the material properties (composite, matrix, and fiber) for the current unidirectional composite.
SUBROUTINE HELIUS2_ELASTIC(HMAT, HPROP, ELASTIC)
INTEGER(INT_PTR_KIND()), INTENT(IN) :: HMAT, HPROP
REAL(8), INTENT(OUT) :: ELASTIC(12,3)
ENDSUBROUTINE
This array will be updated with the composite, matrix, and fiber elastic properties. The first column (ELASTIC(:,1)) contains the composite properties, the second and third columns contain the matrix and fiber properties respectively. Rows 1-12 contain the following elastic properties in order: E11, E22, E33, ν12, ν13, ν23, G12, G13, G23, α11, α22, α33. This will always return the undamaged elastic constants.
