Displacement fields of wood in tension based on image processing: Part 2. Crack-tip displacements in mode-I and mixed-mode fracture

Silva Fennica, 2000
Near tip displacement fields for tensile loaded cracked rubber and wood with a crack parallel-, perpendicular-to-grain, and a parallel-to-grain crack inclined 30°, 45°, and 60° to the load axis were obtained from digital image correlation (DIC ...

Crack paths in soft thin sheets

Fracture and Structural Integrity, 2019
Highly deformable materials (elastomers, gels, biological tissues, etc.) are ubiquitous in nature as well as in technology. The understanding of their flaw sensitivity is crucial to ensure a desired safety level.

Multiparametric presentation of the crack-tip fields in the vicinity of longitudinal shear crack

Вестник Самарского университета: Естественнонаучная серия
The article is devoted to the study of the stress field at the tip of a longitudinal shear crack based on a multiparametric asymptotic representation of the stress field at the crack tip in a linearly elastic isotropic material.

Evaluation of Fracture Parameters for Cracks in Coupled Thermoelasticity for Functionally Graded Materials

Journal of Mechanical Engineering, 2015
The finite element method (FEM) is developed for coupled thermoelastic crack problems if material properties are continuously varying. The weak form is utilized to derive the FEM equations. In conventional fracture theories the state of stress and strain

Tip Crack Imaging on Transparent Materials by Digital Holographic Microscopy

Journal of Imaging, 2019
With this study, we propose a method to image the tip crack on transparent materials by using digital holographic microscopy. More specifically, an optical system based on Mach−Zehnder interference along with an inverted microscopy (Olympus CKX53 ...

THE DECELERATION AND ACCELERATION OF CRACK PROPAGATION FOLLOWING TENSILE OVERLOAD AND HOLD TIME [PDF]

Journal of Engineering Science and Technology, 2018
The effect of the hold time of a tensile overload on crack propagation behaviours following the overload was investigated. In the study, the crack propagation behaviour after the overload was observed under constant amplitude load with stress ratio zero ...
