Definitions

Field Contents SI Unit Example
unit_ID Unit Identifier.

(Integer, maximum 10 digits)

 
shell_ID Element identifier.

(Integer)

 
nb_lay Number of layers.

Must be equal to the number of layers given in the shell property, except for /PROP/SH_ORTH (in this case nb_lay = 1).

(Integer)

 
npg Number of surface quadrature points.

(Integer)

 
ndir Number of orthotropy direction for each layer.

(Integer)

 
Iunit Input angle unit flag.
= 0
Angle in radian
= 1
Angle in degree

(Integer)

 
ϕ i Angle of first direction of orthotropy relatively of first direction of the local reference frame.

(Real)

[ rad ] or [ deg ] if Iunit =1
α i Angle of second direction of orthotropy for layer i, relatively of first direction of orthotropy. Only used for properties /PROP/TYPE16 (SH_FABR) and /PROP/TYPE51.

(Real)

[ rad ] or [ deg ] if Iunit =1

Comments

  1. This option can be used to initialize the orthotropy direction for shells element per element. By default, property defined characteristics are used, those defined using this option are priority.
  2. Local reference frame is described in Local Reference Frame of the Radioss Theory Manual.
  3. This option is compatible only with the orthotropic shell property, like /PROP/TYPE9 (SH_ORTH), /PROP/TYPE10 (SH_COMP), /PROP/TYPE11 (SH_SANDW), /PROP/TYPE16 (SH_FABR) and /PROP/TYPE51.
