    Hi Enriqueng,

     

    Kindly check if the load application is appropriate and rerun the analysis. Can you share the model file which you are using for analysis ? 

     

    Thank you

    Hello PrasannaK,

     

    I have run the analysis several times and the problem persists. I don't know how to check if the load is appropiate; it is just a punctual force aplied in one node of the mesh. I am begining to think that this error has something to do with the PCOMPP, because it is pretty strange that all other stresses are given perfectly. Also, I have tried to change the G13 and G23 properties of the material, and the results vary. If there was not any z13 and z23 stresses the result should be the same.

     

    I am afraid I can not share the model, I am sorry. 

     

    Thank you for your answer, and if there is something else you can share I will be happy to hear it!

    Hi,

     

    I do not think transverse shear stress can be output for plane stress elements. However, composite transverse interlaminar shear stress 1Z and 2Z can be output:

    The transverse shear stress can be output for solid elements:
