The Element Properties form appears when the Element Properties toggle, located on the Patran main form, is chosen.There are several option menus available when creating element properties. The selections made on the Element Properties form will determine which element property form appears, and ultimately, which PAMCRASH element will be created.
The following pages give an introduction to the Element Properties form, and details of all the element property definitions supported by the Patran PAMCRASH Preference.
Element Properties Form
This form appears when Element Properties is selected on the main form. There are
four option menus on this form (under Dimension), each will determine which PAMCRASH element type will be created, and which property forms will appear. The individual property forms are documented later in this section. For a full description of this form, see
Element Properties Forms (p. 61) in the Patran Reference Manual.
The following table outlines the option menus when Analysis Type is set to Structural. Note that not all material types are supported for all properties. This is a function of PAMCRASH.

0D Mass
This subordinate form appears when the Input Properties button is selected on the Element Properties form when the following options are chosen.
Action | Dimension | Type | Option(s) | Topologies |
Create | 0D | Mass | | Point |
Use this form to create a MASS__/_ data entry. This defines added mass for the structural model.
Beam
This subordinate form appears when the Input Properties button is selected on the Element Properties form when the following options are chosen.
Action | Dimension | Type | Option(s) | Topologies |
Create | 1D | Beam | | Bar/2 |
Use this form to create a BEAM___/_ entry. The area and other data is written to a Material Type 200/201/212 record.
Rod
This subordinate form appears when the Input Properties button is selected on the Element Properties form when the following options are chosen.
Action | Dimension | Type | Option(s) | Topologies |
Create | 1D | Rod | | Bar/2 |
Use this form to create a BAR___/_ entry. The area and membrane damping data is written to a Material Type 200/201/202 record.
Linear Spring
This subordinate form appears when the Input Properties button is selected on the Element Properties form when the following options are chosen.
Action | Dimension | Type | Option(s) | Topologies |
Create | 1D | Spring | | Bar/2 |
Use this form to create a BAR___/_ and a simplified Material Type 204 entry.
Shell
This subordinate form appears when the Input Properties button is selected on the Element Properties form when the following options are chosen.
Action | Dimension | Type | Option1 | Option(2) | Topologies |
Create | 2D | Shell | Homogeneous | Uniform Underintegration Hughes-Tezduyar | Tria/3, Quad/4 |
Laminate | Hughes-Tezduyar Uniform Underintegration |
Use this form to create a SHELL___/_ entry. The data is written to a Material Type 100/101/102/103/105/106 record.
Note: | No orientation section is required as only laminated shells have directional properties. Note also that both shell options (Uniform Underintegration/Hughes-Tezduyar) require the same data. |
Use this form to create a SHELL_ _/_ entry. The data is written to a Material Type 130 record.
Solid
This subordinate form appears when the Input Properties button is selected on the Element Properties form when the following options are chosen.
Action | Dimension | Type | Option 1 | Option 2 | Topologies |
Create | 3D | Solid | Hourglass Viscous Base | Uniform Underintegration | Tet/4, Wedge/6 Hex/8 |
Selective Reduced Integration |
Hourglass Viscous Shape | Uniform Underintegration |
Selective Reduced Integration |
Hourglass Stiffness Shape | Uniform Underintegration |
Selective Reduced Integration |
Use this form to create a SOLID_/_ entry. The data is written to a Material Type 1/2/5/99 record.
