REBAR LAYER

*
REBAR LAYER: Define layers of reinforcement in membrane, shell, surface, and
continuum elements.
This option is used to define one or multiple rebar layers in mem brane, shell, and surface elements. It must
be used in conjunction with the
*
MEMBRANE SECTION, the
*
SHELL SECTION, or the
*
SURFACE
SECTION option. Rebar layers in solid (continuum) elem ents can be defined by embedding a set of surface or
membrane elements with rebar layers in a set of host continuum elements through the use of the
*
EMBEDDED
ELEMENT option.

Optional parameters:
GEOMETRY
Use this parameter to specify the type of rebar geometry.
Set GEOMETRY=CONSTA NT (default) if the rebar spacing in the elem ent is constant. The
spacing is given as a length measure on the data lines.
Set GEOMETRY=ANGULAR if the rebar spacing increases linearly as a function of the
distance measured from the axis of revolution in a cylindrical coordinate system. The spacing is
given as an angular spacing in degrees on the data lines. A cyl indrical orientation system must be
defined if this option is used with three-dimensional mem brane, shell, or surface elem ents.
Set GEOMETRY=LIFT EQUATION if the rebar spacing and orientation within the element is
determined by the tire “lift” equation. The rebar parameters are defined with respect to the uncured
or “green” tire configuration, and the lift equation maps the rebar parameters to the cured tire
configuration. The spacing is given as a length measure on the data lines. A cylindric al orientation
system must be defined if this option is used with three-dimensional membrane, shell, or surface
elements.
