The Breakdown of Linear Elastic Fracture Mechanics near the Tip of a Rapid Crack
We present high resolution measurements of the displacement and strain fields near the tip of a dynamic (Mode I) crack. The experiments are performed on polyacrylamide gels, brittle elastomers whose fracture dynamics mirror those of typical brittle ...

Measurement of Displacement Fields around Crack Tip in Brittle and Ductile Polymers.
Moire interferometry was utilized to study fracture behavior of polymer specimens under mode I loading. Displacement fields around a crack tip were experimentally determined for two kind specimens of brittle and ductile polymers. The results were compared with the displacements given by linear fracture mechanics or HRR fields to study their ...

Experimental evaluation of plasticity-induced crack shielding from crack tip displacements fields
In this work it is proposed a methodology for the evaluation of plasticity-induced crack shielding from the analysis of the crack tip displacements fields measured by digital image correlation. This methodology is based on the evaluation of the stress intensity factors determined from the displacements fields measured at the vicinity of the tip of a ...

Predicting fatigue crack growth rate in a welded butt joint: The role of effective R ratio in accounting for residual stress effect [PDF]
A simple and efficient method is presented in this paper for predicting fatigue crack growth rate in welded butt joints. Three well-known empirical crack growth laws are employed using the material constants that were obtained from the base material ...

A Fourth Order Formulation of DDM for Crack Analysis in Brittle Solids [PDF]
A fourth order formulation of the displacement discontinuity method (DDM) is proposed for the crack analysis of brittle solids such as rocks, glasses, concretes and ceramics.

Contrary to J-integral values calculated from the 2D numerical model, calculated J-integrals [1] in the 3D numerical and 3D experimental cases are not very close with J-integral used in the literature.

Quasicontinuum simulation of fracture at the atomic scale [PDF]
We study the problem of atomic scale fracture using the recently developed quasicontinuum method in which there is a systematic thinning of the atomic-level degrees of freedom in regions where they are not needed.
