Mahdi Khadem If you designed them as shell elements and defined a thickness for them, you could see the stress on them by activating 'render shell thickness' box in 'ODB display options' and using 'view cut manager'.

Emre Sengul Dear Emre! thank you for your response. The method you mentioned visualizes the stress only on the shell elements (in-plane) not within the elements (along the thickness after rendering. Any suggestions? thanks

Mahdi Khadem I understood the situation now. FE analysis tools like Abaqus makes the stress calculation using nodes, stress distribution cannot be found in an element because of that there is no another node in this element to define this stress distribution. In other words, you cannot see the distribution in an element directly and you should divide it into elements (mesh) to obtain the distribution. You can look at sub model applications. After solving the big model, these values can be transferred into the sub model. Thus, you can analyze the element in details in order to find the stress distribution.
