Macro-micro dual scale crack model linked by a restraining stress zone with a linear distribution 作者:Tang, XS (Tang, X. S.)[ 1 ] ; Gao, CH (Gao, C. H.)[ 1 ] THEORETICAL AND APPLIED FRACTURE MECHANICS 卷: 71 頁: 31-43 特刊: SI DOI: 10.1016/j.tafmec.2014.01.006 出版年: JUN 2014 查看期刊信息 摘要 Material in a macro-crack tip zone would suffer to some extent damage under loading condition. This can be described by a restraining stress zone in which the distribution of restraining stresses would depend on the material damage. In order to consider the microscopic effects, a micro-notch is attached to the macro-crack tip. Thus, a macro-micro dual scale damage model is established. A linear distribution of restraining stresses is assumed in this work including three cases. Cases A, B and C are, respectively, a right triangle shape, uniform distribution and left triangle shape. Muskhelishivili approach is employed to solve the problem. Obtained are the stress intensity factors (SIF) both at the macro- and micro-scale, crack opening displacement (COD) and strain energy densities (SED) in the analytical form. Numerical calculations are performed. The results show that there is a complicated interaction between the macro-crack and micro-defect. In addition, the distribution of restraining stresses has a large influence on the SIF, COD and SED. (C) 2014 Elsevier Ltd.

Accession number: 20151300692296 Title: A model of moving crack with a linear distribution of restraining stresses in crack tip zone Authors: Tang, Xue-Song1; Chen, Min-Wei1; Gao, Chang-Hui1 Author affiliation: 1 Department of Mechanics, School of Civil Engineering and Architecture, Changsha University of Science and Technology, Changsha, China Source title: Zhendong yu Chongji/Journal of Vibration and Shock Abbreviated source title: J Vib Shock Volume: 34 Issue: 3 Issue date: February 15, 2015 Publication year: 2015 Pages: 183-187 Language: Chinese ISSN: 10003835 Document type: Journal article (JA) Publisher: Chinese Vibration Engineering Society Abstract: The analytical solution of moving Griffith crack model with a constant speed is well known as Yoffe solution. For a static crack, its strip yielding model is well known as Dugdale model. It is found that when Dugdale model is generalized to the moving crack case, the crack opening displacement (COD) is discontinuous and approaches to positive and negative infinite at Rayleigh wave speed. Here, a restraining stress zone was attached to the crack tip while two speed effect functions were introduced assuming the restraining stress zone has a linear distribution. The complex function approach was employed to solve the problem. Analytical solutions of dynamic stress intensity factor (SIF) and crack opening displacement (COD) were then obtained. The new COD result was continuous and finite at Rayleigh wave speed. Some numerical results of COD were presented. Some valuable conclusions were obtained. ©, 2015, Chinese Vibration Engineering Society. All right reserved.
