Hello Achilleas,


 


One added item.  The ISS in composites can have some very high gradients (singular) at free edges and this can be seen by diving into the equilibrium equation. The mesh needed is tiny to often see this phenomenon, just as a note - you may not be interested in edge effects.  Some colleagues have put together this nice article which you should refer to on the topic of ISS in composites.
