| 书目名称 | Fracture and Fatigue Emanating from Stress Concentrators | | 编辑 | G. Pluvinage | | 视频video | | | 图书封面 |  | | 描述 | A vast majority of failures emanate from stress concentratorssuch as geometrical discontinuities. The role of stress concentrationwas first highlighted by Inglis (1912) who gives a stressconcentration factor for an elliptical defect, and later by Neuber(1936). With the progress in computing, it is now possible to computethe real stress distribution at a notch tip. This distribution is notsimple, but looks like pseudo-singularity as in principle the powerdependence with distance remains. This distribution is governed by thenotch stress intensity factor which is the basis of Notch FractureMechanics. Notch Fracture Mechanics is associated with the volumetricmethod which postulates that fracture requires a physical volume.Since fatigue also needs a physical process volume, Notch FractureMechanics can easily be extended to fatigue emanating from a stressconcentration. | | 出版日期 | Book 2003 | | 关键词 | design; fracture; fracture mechanics; mechanics; symbols | | 版次 | 1 | | doi | https://doi.org/10.1007/1-4020-2612-9 | | isbn_softcover | 978-90-481-6417-2 | | isbn_ebook | 978-1-4020-2612-6 | | copyright | Springer Science+Business Media Dordrecht 2003 |
