Question
What do the components of Plate Member force mean?
Answer
The meaning of the member forces from the analysis of the plate element is as follows.
When the element's local axis is set as shown in the following figure:
| Fxx | Tension/Compression force in the local x-direction. Corresponds to the axial force Fx of the beam element. |
|---|---|
| Fyy | Tension/Compression force in the local y-direction. |
| Mxx | Bending moment in the local x-direction. Corresponds to the bending moment My of the beam element. |
| Myy | Bending moment in the local y-direction. |
| Vxx | Shear force in the x-direction. Corresponds to the shear force Fz of the beam element. |
| Vyy |
Shear force in the y-direction. |
The structural behaviors in the y direction such as Fyy, Myy, Vyy are result components that cannot be expressed in beam elements. Therefore, if the structural behavior in the y-direction needs to be checked, then plate modeling is recommended.
