/PROP/TYPE43 - Solid Element Property for Connection Material
Description
This property may only be used with /MAT/CONNECT material law. It is designed for spotweld, welding line or glue type connections.

Strain formulation flag
(Integer)
= 0: default, depends on what value is defined in /DEF_SOLID (Comment 5)
= 1: small strain from time =0. The initial area of the element middle surface is used to calculate nodal forces from element stress.
= 4: full geometric nonlinearities (/DT/BRICK/CST has no effect)
|
|
True_thickness
|
Overwrites the thickness of the solid element.

| 1. | This property is compatible with 8-node brick elements (/BRICK) only which is defined as: |
It is only compatible with material law /MAT/CONNECT.
| 2. | The element does not compute its own time step. The stability is assured by nodal time step in every case (even if elementary time step is generally used). |
| 3. | The element is designed to be connected to other shells or solid elements. Its nodes may also be slaves of a rigid body (/RBODY) or slave nodes of kinematic tied interface (/INTER/TYPE2). |
If several of its nodes are independent/disconnected, one must pay attention to the resulting time step, especially if the element has null or small height and/or mass density. It may result on very small or null nodal time step.
| 4. | The height of the solid element (length in local z direction) can be null. |
| 5. | If Ismstr=0 in /PROP/TYPE43, the Real Ismstr value depends on the Ismstr defined in /DEF_SOLID (see below). Ismstr=10 is the total strain, which is not supported by /PROP/TYPE43, so here Ismstr=4 is used. |
