Zusammenfassung:Wepresnet a brief introduction of applying the idea of mortar method to locally non-conforming TRUNC element for solving plate bending problem. At the interfaces, three mortarconditions, one for the value of solution in pointwise way, the other two for the normal and tan-gential derivatives of the solution in projection way, are provided to secure the global conver-gence. A fte some detailed analysis, we obtain that its error estimates in both energy norm and dis-crete H1 norm are optimal for u* ∈ H3 (Ω)∩ H20(Ω).
