1 The keypads, he says, often break because fatigue fractures appear in the circuit boards of phones.

2 In addition the features of temperature low cycle fatigue fracture surfaces are given.

3 This paper analyses the reason of fatigue fracture of main shaft of horizontal scraper centrifuger by EPMA and optical metallograph.

4 It comes to the conclusion that the corrosion fatigue fracture of LC4 aluminum alloy is the results of combined action of anodic dissolution, hydrogen embitterment (HE) and mechanical damage.

5 The reason of fatigue fracture at a tightening pillar on 8 MN aluminium profile press was analyzed.

6 Fracture morphologies of TIG welds show that the fatigue fracture occurs from weld defects.

7 The results showed that the thermowell was fatigue fracture. The content of sulfur element is over standard and the high temperature promoted the fracture jointly.

8 So,[] the sucker rod's main failure modes are fatigue fracture and corrosion fatigue crack.

9 The graphite in bad morphology speeds up the fatigue fracture process.

10 The authors conclude that spondylolysis is mainly the fatigue fracture due to locally increased stress and is contributing most by backward extension of lumbar spine.

11 The primary failure model is fatigue fracture that is always resulted by the crack initiation and propagation.

12 The result of the test shows that the fatigue fracture areas of all specimens are in the welded toe and the fatigue life of cruciform joint is obviously lower than that of butt joint.

13 The fatigue fracture of test alloys has mixed - rupture characteristics of quasi - cleavage and dimples.

14 The results show that the fatigue fracture is caused by exceeded-quota sulphur and non-metallic inclusion enrichment in crack initiation, which induces stress concentrator in application.

15 The results indicated that fatigue fracture of the wire rope resulted from the secondary quenching caused by abnormal gliding friction of its surface.

16 The fatigue fracture characteristics were fatigue striation, ductile microvoid,() and quasi-cleavage-like fracture characteristic.

17 The fatigue fracture surface of test specimens shows hybrid - fracture characteristics of quasi - cleavage and dimple.

18 The results showed that two shafts'fracture are both - low cycle fatigue fracture caused by vibratory fatigue.

19 The result indicates that the fracture of the drive countershaft is fatigue fracture.

20 The failure of most valve springs is due to the appliedstress resulting in the fatigue fracture.

21 By means of fracture analysis, we found there are clearly morphology of fatigue fracture.

22 Common injuries in basketball include patella chondropathy, "basketball knee", ankle joint injury, waist muscle injury, lower waist pain, heel tendon peripheral inflammation and fatigue fracture etc.

23 Summary of Background Data. Spondylolysis is thought to be caused primarily by a fatigue fracture and spondylolytic tissue has been recognized as being a fibrocartilaginous mass.

24 The result indicates that the chamfer angle and the inclusion are the main reason for the fatigue fracture.

25 If the injury is not cured in time or is cured unsuitably, it will lead to periosteum hyperplasia or incurable fatigue fracture.

26 Fastener common failure mode of failure of the assembly has elongated, fatigue fracture and delayed fracture.
