A new displacement-based approach to calculate stress intensity factors with the boundary element method [PDF]

, 2015
The analysis of cracked brittle mechanical components considering linear elastic fracture mechanics is usually reduced to the evaluation of stress intensity factors (SIFs).

Measurement of Displacement Fields around Crack Tip in Brittle and Ductile Polymers.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 1996
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

Frattura ed Integrità Strutturale, 2015
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 ...

The Breakdown of Linear Elastic Fracture Mechanics near the Tip of a Rapid Crack

, 2008
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 ...

Targeted modulation of IGFL2‐AS1 reveals its translational potential in cervical adenocarcinoma

Molecular Oncology, EarlyView.
Cervical adenocarcinoma patients face worse outcomes than squamous cell carcinoma counterparts despite similar treatment. The identification of IGFL2‐AS1's differential expression provides a molecular basis for distinguishing these histotypes, paving the way for personalized therapies and improved survival in vulnerable populations globally.

Harnessing Fungal Biowelding for Constructing Mycelium‐Engineered Materials

Advanced Engineering Materials, EarlyView.
Mycelium‐bound composites (MBCs) offer low‐carbon alternatives for construction, yet interfacial bonding remains a critical challenge. This review examines fungal biowelding as a biocompatible adhesive, elucidating mycelium‐mediated interfacial mechanisms and their role in material assembly. Strategies to optimize biowelding are discussed, highlighting

Experimental and numerical in-plane displacement fields for determine the J-integral on a PMMA cracked specimen

EPJ Web of Conferences, 2010
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.
