Abstract: This paper presents an investigation of the line-spring model (LSM) of Rice and Levy as applied to nonlinear crack problems. A J 2 deformation theory of plasticity formulation of a LSM for ...

Abstract: Crack initiation, stable growth, instability and crack opening behavior in flawed 304 SS piping has been examined within the framework of the engineering approach developed by Kumar, German and ...

Abstract: This paper presents elastic analysis of axial and circumferential semielliptical surface flaws in cylinders using the line-spring model of Rice and Levy [1-3] and a shell finite element method. ...

Abstract: The calculation of the energy release rate, G , by the virtual crack extension method has been used extensively in the literature over the last few years. A formulation and implementation of ...
