Abstract:	圓形環中裂縫存在的位置，強烈的影響受力增加時，塑性鉸生成的位置與順序，進而影響環的穩定性的理論解[1]，以及數值解[2]，都已經有了結果，但實驗的部分確尚未得到，本論文的首要目的就是要以實驗的結果。在工業界而言，一般裂縫大都會發生在管壁的內部，所以，本論文的第二個目的便是應用邊界元素法，將理論[1]與數值解[2]的管壁外圍裂縫改為內部，由於原本所施的應力為反向壓力，而造成大多數的內部裂縫會閉鎖，也因此，受力情形將改為反向拉力，以確保裂縫是張開的狀況。實驗結果當然是用來驗證理論及數值的部 The location of a outer crack can strongly affect the sequence of plastic hinge development which in tern affects stability of a circular ring which has been obtained theoretically in Young [1] and numerically in Young [2] but not any experimentally.
