Plate result intrepretatoin

Question:

Hi,

When we try to pull the results from Results tables for plates, we see the following -Forces (Global), forces (Local) and Forces (unit length). While forces (Global) and forces (Local) refers to the force along that direction, it is not clear what the Forces (Unit length) is, how it is related to the Forces (Global or Local) and what is its impact on result interpretation.

Please advise.


Answer:
For example consider the below case,

The loads listed are being applied on this meshed plate.



Now ,
 
Force refers to the internal forces developed at each node due this load applied.

Say if I am want to isolate a corner element, and get the forces developed at the node, then one will have to refer to Force (local or Global).
So these are basically the internal forces for the element.


These forces cause stresses in the plate referred under Results tables > Plate Stresses (local & global)

From these stresses what is derived is the Force per unit length which is generally used for design.
The details of which is given below.










Hope this helps. Do let us know if any further clarification if required.
