    Hi,

     

    You can use Free body diagram module to calculate shear force and bending moment. Please refer to OptiStruct help for more details on the same.

    Hi Prakash,

    I want to calculate at pre-processing stage. Is there any possibility?

    Yes, it's possible with .... 'Strength of Materials' course!

    Please, understand my requirement.

    I have nodes, material and thickness. Now, from hypermesh can i calculate section force and thickness at preprocessing stage??

    Hi @Jouher

     

    Not sure what you mean by at PREPROCESSING stage means, but FBD is also used to extract cross-sectional resultant forces and moments (typically at the centroid of a cross-section) for use in traditional strength calculations.

    Hello @Jouher,

    Greetings!!

     

    When you say preprocessing stage, do you mean applying a  pre-load to a component/part? 

     

    If that's the case, you might want to look into the topic of explicit dynamic relaxation.

    http://ftp.lstc.com/anonymous/outgoing/jday/bolt_preload3.pdf

     

    If you are using LS-Dyna, you can have created a output file, wherein you can extract the data before the actual simulation begins (i.e during pre-load period).

     

    You can find something similar for RADIOSS I believe. (>DYREL option)

     

    Please, let us know, if you find a proper solution.
