You may try to check von Mises stress value and compare it with the limit one.

Compare the value of stress from the map with the resistance of the steel grade you used as a material of the plate.

Hi,

I have a question regarding a similar plate, but it’s a topplate for a pile. To design this plate I have modelled a planar fixed support under the plate to indicate the pile. When you use von mises stress value, does is it take into account the thickness of the plate and the distribution of the support reaction to the center of the plate?

Or do I have to model a bigger support to take into account the distribution of the load?

I hope the drawing above explanes my question better.

Mind that a shell doesn't have 'real' thickness which is just its attribute (as a profile for a bar element). If so you either need to increase the size of the support or decide to use a solid model instead.

Greetings , just wanted to know if this method is used is there a need to compare the stresses with the yielding stress multiplied by a reduction factor

for example 0.9* fy or 0.75 fy ?

Hi @me1205377

Yes, with whatever limit (including safety/material factors) which is applicable for the particular design you are performing.
