A Comparison of CMOD-Based CTOD and <i>J</i>-Conversion CTOD in Shallow Crack Specimens
, 2010 The ratio of J-conversion CTOD to CMOD-based CTOD was experimentally evaluated and analytically estimated in shallow crack specimens. It was demonstrated that the low strain hardening exponent in the Ramberg-Osgood relation reduced the CTOD ratio. A CTOD

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 8, Page 3404-3419, August 2026.ABSTRACT In this study, the fracture response of polypropylene (PP) was assessed using J‐integral evaluation, J‐R curve construction, and fractography examination. J‐R and load–displacement curves were analyzed to determine critical loads and estimate J‐integral values based on standards established for polymer fracture testing, which led to the ...

Fatigue Crack Growth from Notches: A Numerical Analysis
Applied Sciences, 2020 A numerical approach based on plastic crack tip opening displacement (CTOD) was followed to study fatigue crack growth (FCG) from notches. The identification of fundamental mechanisms was made considering notched and unnotched models, with and without ...
