The Near-Tip Fields of Fast Cracks
Science, 2010Slightly Cracked While there are detailed theories to explain the propagation of a crack in the bulk of a material, our understanding of cracking breaks down near the tip of the crack. Experimentally, it is very hard to observe the propagation of a crack at the tip region because it tends to move very quickly.

Meshless Numerical Simulation of Singular Fields at Crack Tips of Branched Crack
International Journal of Computational Methods, 2021One of the most important tasks in the numerical analysis of the fracture problem is to achieve a high-precision approximation of the singular stress fields at crack tips. Partially or fully enriched basis functions are often used as enhancements on the whole problem domain or just near the crack tips when constructing the meshless shape functions to ...

Crack tip field in thermoelectric media
Theoretical and Applied Fracture Mechanics, 2013Abstract The crack problem in a medium possessing coupled thermoelectric effect under thermal-electric loads is considered in this paper. The crack surfaces boundary conditions are assumed to be electrically and thermally impermeable. The general two dimensional solutions are presented in closed-form based on the complex variable method.

Crack-tip fields in anisotropic shells
International Journal of Fracture, 2002Asymptotic crack-tip fields including the effect of transverse shear deformation in an anisotropic shell are presented. The material anisotropy is defined here as a monoclinic material with a plane symmetry at x3 = 0. In general, the shell geometry near the local crack tip region can be considered as a shallow shell.

Crack-tip fields in a viscoplastic material
International Journal of Solids and Structures, 1987An integral representation for the particle velocity in terms of a Green function and certain linear combinations of the inelastic strain rates has been used in this paper, both for a numerical method to compute full field solutions and to develop unequivocal asymptotic expressions for the fields near a stationary crack tip.

A transverse crack tip field in bimaterial
Acta Mechanica Sinica, 1994The asymptotic field near an interface crack tip is analyzed with the fully nonlinear theory. By dividing the crack tip field into narrowing sectors and an expanding sector, the asymptotic equations for the crack tip field are derived and solved. The singular characters of stress and strain near the crack tip are revealed.

Crack-Tip Field of a Supersonic Bimaterial Interface Crack
Journal of Applied Mechanics, 2002The sextic approach was used to investigate the asymptotic field of a bimaterial interface crack in the entire supersonic regime and extended to include the combination of isotropic and homogeneous materials, where the sextic method had been considered difficult. Application to typical systems was demonstrated.

Near-Tip Field for Diffraction on Square Lattice by Crack
SIAM Journal on Applied Mathematics, 2015The author examines properties of driven elastic waves spreading through an infinite square lattice containing a finite crack. The analysis is focused on wave diffraction and on the induced displacement field at the vicinity of the crack tip. The problem is treated numerically by solving the corresponding discrete Helmholtz equation with prescribed ...
