Load: Temperature Gradient

Function

Enter the temperature difference between the top and bottom of beam or plate elements for thermal stress analysis. Modify or delete previously entered temperature difference.

Temperature gradient analysis is applicable for elements with bending stiffness, such as beam and plate elements. In the case of a beam element, enter the temperature difference and the corresponding distance between the extremities of the element with respect to the local y and z-axes. In the case of a plate element, the temperature gradient can be represented by the temperature difference between the upper and lower faces of the plate and the plate thickness. The gradient temperature produces equivalent moments.

Mode

Add

Add new loads to the selected nodes

Replace

Replace previously defined loads on the selected nodes

Delete

Delete previously defined loads on the selected nodes

Apply to Unassigned Objects Only

When adding new loads, this option applies loads only to the unassigned nodes.
 

Gradient

Enter the temperature gradient information. If the type of plate element is specified, the element local y-direction data will become inactive.
 

T2z - T1z

Temperature difference between the two outermost faces in the local z-direction of the element.
Use Section Hz

Use the previously inputted section dimension information.
Hz

Distance between the two faces in the local z-direction of the element.
T2y - T1y

Temperature difference between the two outermost faces in the local y-direction of the element.
Use Section Hy

Use the previously inputted section dimension information.
Hy

Distance between the two faces in the local y-direction of the element.
