膠粘失效 的英文怎麼說
中文拼音 [jiāoniánshīxiào]
膠粘失效
英文
glue failure-
Rubber components often appear interface failure due to the actions of mechanical loads and the influences of enviorment. hence, in this paper the interface failure mechanism has been studied by means of finite element method and fracture machinics. the numerical results of testpieces deformation with crack are in close agreement with experimental values
橡膠鋼雙材料試件由於機械載荷和環境的影響經常在粘接界面發生破壞而導致結構失效，藉助有限元和斷裂力學對界面破壞機理進行研究，得到的存在初始裂紋的試件變形與實驗結果吻合較好。However, the die attach layer delaminated after 500 cycles and pcb cracked in the underfilled samples after long time cycling. c - sam is employed to investigate the delamination in the underfilled samples. highly concentrated stress - strain induced by the cte mismatch between the bga component and the pcb board, coarsened grain and two kinds of intermetallic compounds ( nisn / nisns ) which formed during reflow and thermal cycle and their impact on the reliability of solder joints are discussed in this paper
充膠樣品粗化尤為嚴重； ? ni - sn金屬間化合物包括兩層：其中，靠近ni焊盤的那層比較平整，同時， eds結果分析表明其化學式近似為nisn ，而靠近焊料的那層呈板條狀，化學式近似為nisn _ 3 ，文獻表明其為亞穩相； ?充膠使得樣品最大應力范圍降了接近一個數量級並降低了dnp的作用，同時，器件失效模式變為晶元粘接層分層； ? c - sam結果表明本論文採用的充膠樣品，晶元粘接層分層起始於500周左右，而經過2700周循環的樣品，分層幾乎擴展到整個界面。Moreover, we notice that failure of the bonding interface between frp and concrete is one of the main failure modes
注意到當前混凝土梁板加固中frp與混凝土之間膠縫粘結破壞是加固失效的主要模式之一。Taking gear without tooth face invalidation such as agglutination and abrasion as a precondition, and according to the relation between minimal oil film thickness and tooth face roughness of elastic liquid dynamic pressure lubrication theory, viscosity of gear lubrication oil was educed by reliability method in this paper, and the calculation formula has been elicited and applied
摘要以齒輪傳動不發生膠合、磨損等齒面失效為前提，根據彈性流體動壓潤滑理論的最小油膜厚度與齒面粗糙度的關系，用可靠性方法確定齒輪潤滑油的粘度，給出計算公式並進行了實例計算。This paper investigates 15 r. c. beams under different conditions of cfrp amount, anchor condition and load history. the experiment results show that the flexural strength, stiffness and cracking behavior of rc beams can be improved. a failure mode caused by epoxy - concrete interface bond abating is observed and analyzed in this paper
