Products: Abaqus/Standard Abaqus/Explicit
Specifying section properties for shell elements using the general shell section definition is verified in the following tests. An S4R element is subjected to simple shear with monotonically increasing loads. The analysis consists of a sequential transfer between Abaqus/Explicit and Abaqus/Standard and back to Abaqus/Explicit. The material parameter is used to define linear isotropic elastic behavior for a general shell section. The composite parameter is used to define orthotropic elastic properties for a shell composed of different linear elastic layers.
The following linear elastic properties are used (the units are not important):
The orthotropic material properties are
 = 200 × 109 |
 = 100 × 109 |
 = 100 × 109 |
 = 0.3 |
 = 0.23 |
 = 0.34 |
 = 76.9 × 109 |
 = 76.9 × 109 |
 = 9.0 × 109 |
| Density = 7850. |
Verification tests of the enhanced hourglass control method are also included.

Specifying section properties for shell elements using the general shell section definition is verified in the following tests, which involve a sequential transfer from one Abaqus/Standard analysis to another. During the first analysis the element is subjected to simple shear by monotonically increasing loads during a static procedure. The results from the end of the first analysis are transferred to a second analysis. During the second analysis a new element is defined and both elements are subjected to the same final loads in a static step. The material state is imported, and the reference configuration is not updated. The material parameter is used to define linear isotropic elastic behavior for a general shell section. The composite parameter is used to define orthotropic elastic properties for a shell composed of different linear elastic layers.
