摘要

研究了在横向上具有光滑(连续)材料不均匀性的棒材纵向裂纹。该杆的横截面为圆形。纵向裂纹沿杆的厚度任意分布。假设拉伸和压缩弹性模量在横向上连续分布，推导出应变能释放率的解。采用柔度法对应变能释放率进行了分析验证。对裂纹位置、材料的不均匀性以及材料在拉伸和压缩中的不同力学行为等因素对断裂的影响进行了详细的研究和讨论。

Lengthwise Fracture Study of Transversely Inhomogeneous Rods

A lengthwise crack in a rod that exhibits smooth (continuous) material inhomogeneity in the transverse direction is studied. The rod has a circular cross-section. The lengthwise crack is located arbitrarily along the thickness of the rod. A solution to the strain energy release rate is derived assuming that the moduli of elasticity in tension and compression are distributed continuously in the transverse direction. The strain energy release rate is also analyzed by applying the compliance method for verification. The influences of various factors such as the crack location, material inhomogeneity and the different mechanical behavior of the material in tension and compression on the fracture are investigated and discussed in detail.

期刊介绍： Engineering Transactions (formerly Rozprawy Inżynierskie) is a refereed international journal founded in 1952. The journal promotes research and practice in engineering science and provides a forum for interdisciplinary publications combining mechanics with: Material science, Mechatronics, Biomechanics and Biotechnologies, Environmental science, Photonics, Information technologies, Other engineering applications. The journal publishes original papers covering a broad area of research activities including: experimental and hybrid techniques, analytical and numerical approaches. Review articles and special issues are also welcome. Following long tradition, all articles are peer reviewed and our expert referees ensure that the papers accepted for publication comply with high scientific standards. Engineering Transactions is a quarterly journal intended to be interesting and useful for the researchers and practitioners in academic and industrial communities.
