how to view stress variation inside a 4 nodes plane element

i'm an engineering student and I studied that the stress xx value in a plane 4 node element should vary linearly with the y coordinate and so should do the stress yy in the x direction, does anyone know how to see the stress gradient inside a single element? (e.g. with a control card or I don't know how)

cause averaging method is nosense in this case since i want to know the values of stress inside that element without carying of what happen near to that element.

thanks in advance.

    Hi Teo_s

    Plot the result as shown in the below image to get the stress value in the xx direction

    Hello,

     

    You have to switch on the corner stress results ('Use corner data').

    Be sure that the result file also includes the corner stresses, e.g. STRESS(H3D,ALL,CORNER) = ALL

     

    Best Regards,

    Mario
