FM2009 is held in Chengdu， Sichuan Province，from October 16 to October 20， 2009. The first FM conference was held in 2003 at East ChinaUniversity of Science and Technology， Shanghai. Since then， the FM annual meetings have taken placeat different cities in China. This includes FM2004 in Huangshan， Anhui Province， FM2005 in Zheng zhou， He nan Province， FM2006 in Nanjing， Jiangsu Province， FM2007 in Changsha， Hunan Province and FM2008 in Hangzhou， Zhejiang Province. These annual events are indicative of the fact that the FM symposium series has played an important role in promoting information exchange，inspiring new ideas， integrating practical and research findings and breaking new grounds for the younggeneration.　　As the globe is evolving into a more complex world， the structural integrity technology should adaptto the challenges of complexity of the environments and the machines themselves. An examination of thetransferability and applicability of the current mechanics approaches or theories to practical applicationsshould be imperative. As is known to us， any new model or approach must successfully transit twosequential \"filters\" between research initiation and application， i.e. a technical filter（does it work？）and atechnological filter （does it make sense in the \"real world\"？）.However， our mechanics researchcommunity is normally not sufficiently knowledgeable concerning the metrics of the technological filterand therefore \"non （application） useful\" research is conducted in many cases and in others the research isnot carried far enough to allow practical applications.Aiming at bridging the gap between fundamentalresearches and applications， FM2009 brings together the mechanics research community and theapplication community to identify the transferability and applicability of current mechanics approachesfor structural integrity assessment.　　The symposium （FM2009） is co-organized by Southwest Jiaotong University， East China Universityof Science and Technology， National Engineering Research Center of Pressure Vessels and PipelinesSafety Technology （General Machinery Research Institute）， Nanjing University of Technology， ZhejiangUniversity， Zhejiang University of Technology， Zhengzhou University， Changsha University of Scienceand Technology and Shandong University， and co-sponsored by the Chinese Consortium of StructuralIntegrity（including members of Chinese Pressure Vessel Institution and the High Temperature Strengthof Materials Committee of Chinese Materials Institution），Natural Science Foundation of China andGeneral Administration of Quality Supervision， Inspection and Quarantine of China.　　On behalf of the organizing committee， we would like to thank the above co-organizers andco-sponsors who made FM2009 possible.We also appreciate the efforts of the steering committeemembers in reviewing and selecting the papers. We are grateful for Professor George C. Sih for hisconstant support to the symposium series. We are indebted to Professor Zhengdong Wang and Dr ChiTsieh（Jimmy）Liu for their passion to the symposium and efforts made to ensure the success of the event.Special thanks are also due to the authors and speakers who make FM2009 unique.精彩书摘 　　chemical kinetics process [4]. Nevertheless, thedamage or deterioration process of material is nota simply elementary reaction. It is composed ofhighly complicated reactions of a series of dif-ferent barriers. Hence, the activation energy dur-ing the deterioration process of materials is afunction of temperature and time. This is differentfrom the preconditions of the classical Arrheniusequation. Therefore, whether Arrhenius equationis applicable to describe the deterioration processof materials under different time scales needsfurther theoretical research and experimental va-lidation [5]. There are similar bottleneck prob-lems regarding the life prediction of deformationand fracture of materials under chemical attack,which require us to understand the synergeticeffect of mechanics and chemistry [6].　　Another emerging issue is in life prediction thetime dependent fracture under complex stressstate or constraint. The actual engineering struc-tures or components are rather complicated. Forexample, there can be structural discontinuity,material discontinuity and load discontinuity re-quired by service functions or introduced bymanufacturing processes. The response to frac-ture of the structures can be very different fromthe behavior obtained from small specimens in the lab. On the other hand, in order to evaluate the service properties of actual structures, it isgenerally very difficult to remove a bulk materialfrom the structure. Thus non-standard specimensare machined from the structures resulting in dif-ferent constraints. Obviously the key would be todescribe the actual failure process under con-straints （under complicated stress status）. In orderto transfer the experimental results in labs to en-gineering components, lots of efforts have beentaken to study the constraint effect on fracture atambient temperature. It was recognized that thefracture toughness is no longer a constant unlessthe stress flied near the crack tip is dominated bygeneral fracture parameters （stress intensity factorK or J-integral） [7]. But in fact the structurethickness and crack dimension could hardly sat-isfy the constraint requirements near the crack tipand thus the fracture toughness tested fromhigh-constraints samples in the lab cannot be di-rectly used in engineering structures. Aiming atsuch shortcomings, a number of approaches in-cluding K-T method applicable to linear elasticfracture, J-Q theory under elastoplastic mecha-nism and three-parameter revision method, havebeen proposed [8]. Meanwhile, local approachbased on Weibull stress and some other improvedmodels have been proposed for the brittle fractureproblems of thick components [9]. However, thetime-dependent fracture under constraint effect isstill a challenge issue. Much work should be doneto quantify the time dependent constraint effect,develop the non-standard testing methods, andclarify the transferability of testing results. Anemerging issue is to develop the micro-or minia-ture specimen testing method that can be used forthe semi-destructive evaluation of service struc-tures. At present, some research work has beendone on obtaining the high-tempera~re creepproperties by using non standard specimens. Forexample, indentation test can be used to measurethe creep and fatigue properties of material （i.e.impression creep and compressive fatigue） inaddition to general mechanical properties [10].Small punch test has been well used in Europeand testing standard has been proposed [11]. Atesting method based on ring specimen that usesthe reference stress to correlate the experimentalresults with uniaxial ones has been proposed re-cently [12]. In fact, the specimens used for ob-taining the material properties of service compo-nents can be very different （as shown in Fig. 1 ！）.Emphasis should be laid on the time-dependentdeformation and fracture theory under constraintcondition that enables the non-standard specimentest techniques [ 13].　　4. Development trends in life monitoring　　From the view point of epistemology, there areno perfect design and perfect manufacture. Toensure the safe operation, life monitoring of crit-ical industrial equipment should thus be impera-tive. At the same time, the applications of ad-vanced materials and processing technologies inhigh tech products are now common practicesthough lack of testing data and service experi-ences. An on-line life monitoring system willhelp to indentify the problems in the materialsand processing, which in turn gives feedback toimprove materials and design and manufacturebesides securing the safe operation.插图

钥匙头，断了一点点在保险柜锁心里，请问还有什么补救方法吗？用钥匙还能打开吗？只有一点点塞在里面了，
钥匙断点点保险柜锁请问补救用钥匙能打点点塞面面积
提问者采纳
鹰嘴钳 用钥匙断口 合住 用巧劲
…真的解决了嘛？我以前也这么试过
就里面塞了点，半粒米都不到，还有那么多面积，大概用钥匙还能开，影响不大吧，毕竟没有断一半在里面
断一半其实更好开…
取出来就要专业的人了 锁芯那个东西好难弄
哦，断了一点头头在里面，呵呵！大概还能开吧，你觉得呢？我听听你的建议
断口不规则就好开…记得用巧劲 这个是个技术活
嗯嗯，我就是用了小铁丝，掏不出来呢！好麻烦
你可以拍照给我看看
在里面呢，拍不到他
啊哈哈 你在南昌我就能帮你
呜呜，哎！
试试那个断口吧
我不敢了，等备用钥匙
大概问题不大，应该能开
好吧 祝你好运
好的，谢谢

找锁门服务
只要钥匙没弯，应该还能开
找开锁的，100元就下来了
回答完毕，求好评 请送我财富值。跪谢。
用细钢丝想法把那点断头弄出来用备用钥匙就可开的哈
哦，一点点塞里面了，用钢丝没什么用，因为只有一点点在里面，
或许你可以把备匙头上粘一点双面粘插进去把那点粘出来
你用工具取出来，最好换锁，修过的锁都不灵光
一小点在里面了，另一把钥匙叫别人带过来了！我想知道还有用吗？因为只有一点点在里面
你先要把里面东西取出来的，看你了，锁贵重物品最好换锁
嗯，好的!我刚用小灯看了，最里面有一点点!大概钥匙来了就能开的，
你是把钥匙卡断了还是里面有异物
钥匙头，有一点点断在里面了，一粒米大小！大概影响不大吧，备用钥匙一会儿拿来了
打不开吧，用钥匙打不开吧，你已经卡进去一点了，又放新钥匙进去，卡的会更厉害，试试看能不能拿针先捅出去
我试了好几遍，出不来呢
那不行，你拿新钥匙别弄巧成拙了
那不行，你拿新钥匙别弄巧成拙了
先把里面的取出来
我用小铁丝掏不出来
不行，真不能拿新钥匙捅，你可以试试
你有什么可行的补救办法吗？
做个钩子慢慢沟出来，最好有看牙的那种钩子
您好，确定能勾出来？
我的锁子是这么弄的，但最后我还是换锁了，我不是保险柜是防盗门。所以不一样，只能让你试试
好的，谢谢
找开锁的，问题交给专业人士解决。
应该能开的 你试试 ..
赶快换锁这样不安全
