Cyclic loadings

Cyclic loadings
Currently Ple4Win doesn't check cyclic yielding according to the NEN 3650-2:2003+A1:2006 D3.4.

Is it possible to expand this check in a future update of Ple4Win.

We will research the possibility of expanding Ple4Win with this check. Your request is submitted as ticket 920.

Maybe a wizard for this would be handy. This NEN check is only valid for steel pipes.

Let say you have 4 project files with different loadcases (cyclic loadings):

In the wizard all 4 project should be loaded. After this Ple4Win should read the TSTRESS table of all elements for all 4 project files. Re and ReT from DF3.1 are also needed for this check. After this you have enough information to the stress check.

We have created an Excel 2010 sheet for this. I will send it to you. You can give an output table for maximum SMAX for every element, but also a detailed SMAX for every angle in the element (every 7.5 degrees). The SMAX can be then plotted on a polar graph.

Hi Shaswin,

Since the check needs multiple projects, a wizard might indeed be the way to go. Thanks for sharing your knowledge, this gives a clear starting point for your request.
