Products: ABAQUS/Standard ABAQUS/Explicit ABAQUS/CAE
Benefits: Reinforcement spacing can now be defined as a function of radial position in three-dimensional elements. The geometry of the reinforcement can also be defined using the tire “lift equation.”
Description: Cylindrical concrete structures, such as a concrete dome, often contain reinforcement oriented along the radial direction. Such specification of rebar can now be defined more conveniently by providing the angular spacing in degrees as shown in Figure 4–3.
Structural tire analysis is often performed using the cured tire geometry as the reference configuration for the finite element model. However, the cord geometry is more conveniently specified with respect to the “green,” or uncured, tire configuration. The tire lift equation provides mapping from the uncured geometry to the cured geometry (see Figure 4–4). You can specify the spacing and orientation of the rebar cords with respect to the uncured configuration and let ABAQUS map the rebar properties to the reference configuration of the cured tire.
