Abstract
本論文針對古典分片檢驗觀念,提出一個新的數學理論,並以此理論作基礎,對非協調有限單元(Incompatible Eleme nts)及應力混合單元(Hybrid-stree Elements)之建立作一統一之數學解釋。The novel mathematical theories for the patch test are proposedin this thesis. Based on these theori es, the formulations ofsome hybrid stress element s and incompatible elements areexamined in a unif ied manners.
