Nonlinear lattice model of viscoelastic mode III fracture.

We study the effect of general nonlinear force laws in viscoelastic lattice models of fracture, focusing on the existence and stability of steady-state mode III cracks. We show that the hysteretic behavior at small driving is very sensitive to the smoothness of the force law. At large driving, we find a Hopf bifurcation to a straight crack whose velocity is periodic in time. The frequency of th...

Mode-I fracture in a nonlinear lattice with viscoelastic forces.

We study mode-I fracture in a viscoelastic lattice model with a nonlinear force law, with a focus on the velocity and linear stability of the steady-state propagating solution. This study is a continuation both of the study of the piecewise-linear model in mode I, and the study of more general nonlinear force laws in mode-III fracture. At small driving, there is a strong dependency of the veloc...

Steady-state mode III cracks in a viscoelastic lattice model

We extend the Slepyan solution of the problem of a steady-state crack in an infinite ideally brittle lattice model to include dissipation in the form of Kelvin viscosity. As a demonstration of this technique, based on the Wiener-Hopf method, we apply the method to mode III cracks in a square lattice. We use this solution to find the critical velocity at which the steady-state solution becomes i...

Thermal fracture as a framework for quasi-static crack propagation

We address analytically and numerically theproblemofcrackpathprediction in themodelsystem of a crack propagating under thermal loading.We show that one can explain the instability from a straight to a wavy crack propagation by using only the principle of local symmetry and theGriffith criterion.We then argue that the calculations of the stress intensity factors can be combinedwith thestandardcr...

Mode Ii Fracture Behavior of Bonded Viscoelastic Thermal Compressed Wood

The influence of viscoelastic thermal compression (VTC) of wood on bonding performance was studied. Mode-II (shear mode) fracture of the bonded interphase was performed using the overnotched and end-notched flexure methods. The study examined four groups of specimens; a control and VTC specimens with three different degrees of densification (63, 98, and 132%). The specimens were bonded with phe...
