Computing stress intensity factors for curvilinear cracks [PDF]

, 2015
The use of the interaction integral to compute stress intensity factors around a crack tip requires selecting an auxiliary field and a material variation field.

Deformation Fields Measurement of Crack Tip under High-Frequency Resonant Loading Using a Novel Hybrid Image Processing Method

Shock and Vibration, 2018
A novel hybrid image processing method is proposed to obtain the crack tip location, crack propagation path, displacement, strain fields, and plastic zone size of crack tip region under high-frequency resonant loading in this paper.

Influence of the process of damage accumulation on the asymptotic behavior of stress fields under creep conditions of a sample with a central crack

Вестник Самарского университета: Естественнонаучная серия, 2023
The present study describes the influence of the mutual effect of damage accumulation on the stress fields at the central crack tip in the plate subjected to uniaxial tension.

Autonomy and Singularity in Dynamic Fracture

, 2010
The recently developed weakly nonlinear theory of dynamic fracture predicts $1/r$ corrections to the standard asymptotic linear elastic $1/\sqrt{r}$ displacement-gradients, where $r$ is measured from the tip of a tensile crack.

Plecstatin inhibits hepatocellular carcinoma tumorigenesis and invasion through cytolinker plectin

Molecular Oncology, EarlyView.
The ruthenium‐based metallodrug plecstatin exerts its anticancer effect in hepatocellular carcinoma (HCC) primarily through selective targeting of plectin. By disrupting plectin‐mediated cytoskeletal organization, plecstatin inhibits anchorage‐dependent growth, cell polarization, and tumor cell dissemination.

Identification of the plastic zone using digital image correlation [PDF]

Fracture and Structural Integrity, 2014
In this paper Digital Image Correlation (DIC) is used to study the evolution of the plastic zone close to a crack tip. A modified CT-specimen was used in order to fulfill the plane stress condition.
