Crack tip fields in anisotropic planes: a review

Abstract: This paper reviews crack tip asymptotic fields in generic plane anisotropic media, rigorously categorising about 400 studies devoted to the determination of the asymptote coefficients, also referred to as crack tip parameters. These studies cover a broad spectrum of methodologies focused on determining crack tip parameters in anisotropic materials, from analytical, numerical and experimental perspectives, conducted over the last six decades. Brief descriptions are given for a selected number of approaches to s… Show more

“…In addition, the deviation phenomenon of crack direction within a coarse grain can also be analyzed based on the discussion in Section 4.2, combined with finite element simulations of the stress field intensity at the crack tip under different stress modes 41,42 . Figure 15A,B shows the simplified diagrams of the intensity of the stress field at the crack tip for these two propagation modes.…”

“…En los últimos años, los modelos numéricos fractomecánicos han proporcionado herramientas para el cálculo de otros parámetros no singulares, que son incorporados a los criterios de fractura de la Tabla 2.1. Estos enfoques, conocidos como modelos fractomecánicos multiparamétricos, han sido estudiados para materiales isótropos [148,152,153], y anisótropos [154,155].…”

“…Descripción multiparamétrica: El enfoque multiparamétrico introducido se basa en la solución de Williams de la distribución del campo de tensiones en la punta de la fisura. Se muestran que el uso de más términos de la expansión en serie permite expresar el campo de tensiones en la punta de la grieta de manera más efectiva que si solo se considera el primer término, equivalente al factor de intensidad de tensiones [155].…”
