Thickness Data dialog box (Value)

Thickness Data dialog box(Stiffened)

To enter new or additional thickness data

Click in the Properties dialog box and enter the following items :

Value

Thickness ID: Thickness numbers of planar elements (Auto-set to the last thickness number +1)

In-plane & Out-of-plane: Enter a thickness when the in-plane and out-of-plane thicknesses are identical in both directions.

In-plane: Enter a thickness used for the calculation of stiffness in the in-plane direction.

Out-of-Plane: Enter a thickness used for the calculation of stiffness in the out-of-plane direction.

Revision of Ver.7.4.1

Plate Offset :  Offset of a plate section in the element’s local-z direction.

Thickness Ratio : For a specific location of Offset, enter the distance as ratio of the offset distance to the plate thickness.

Note

For example, if the plate thickness is 200mm and thickness ratio is entered as 0.1, offset distance is 20mm. If In-plane thickness is different from Out-of-plane thickness, offset distance is determined based on the In-plane thickness.  

Value : Enter the offset distance directly.

Stiffened

Thickness ID: Thickness numbers of planar elements

Value: Select to define sections by directly entering the data for calculating the stiffness of ribs.

Thickness for Weight: Equivalent thickness for calculating the weight

Rib Position: Rib position relative to planar elements

Lower: Rib placed underside of the planar elements.

Upper: Rib placed upper side of the planar elements.

yz section: Stiffness calculation data of rib placed in the direction of ECS x-axis

xz section: Stiffness calculation data of rib placed in the direction of ECS y-axis

Section Shape List: Select a section shape of the rib.

In-Plane: Enter a thickness used for the calculation of stiffness in the in-plane direction.

Out-of-Plane: Enter a thickness used for the calculation of stiffness in the out-of-plane direction.

Hu. Hl: Refer to the guide diagram on the left side of the dialog box.
