Influence of Material Thickness on the Ductile Fracture of Steel Plates for Shipbuilding

open access: yesPolish Maritime Research, 2022
In the shipbuilding industry, the risk of brittle fractures is relatively high because some units operate in arctic or subarctic zones and use high thickness (up to 100 mm) steel plates in their structures.

Crack Growth in Ni-Cr-Mo-V Steel Using ΔCTOD Elastic–Plastic Model

open access: yesJournal of Marine Science and Engineering, 2022
Many studies have shown that the linear elastic fracture mechanics (LEFM) method based on the stress intensity factor range (ΔK) has limitations that cannot be ignored. Due to neglecting the influence of plastic deformation near the crack tip, LEFM shows

Elastic-plastic defect interaction in (a)symmetrical double edge notched tension specimens [PDF]

open access: yes, 2017
Interaction of defects tends to intensify their crack driving force response compared to the situation where these defects act independently. The interaction between multiple defects is addressed in engineering critical assessment standards like BS7910 ...

Implementation of Recent Advances in Fracture Toughness Testing to Investigate Tearing Resistance of Heat-Resistant Steel 14MoV6-3 [PDF]

open access: yesArchives of Metallurgy and Materials
Since WWII, progress has been made in understanding how materials fail and how to prevent such failures. In this work, the newly standardized Single Edge Notch Tension (SENT) specimen is used to assess the ductile tearing resistance of 14MoV-3 steel ...

A Numerical Study of the Effect of Isotropic Hardening Parameters on Mode I Fatigue Crack Growth

open access: yesMetals, 2020
The consideration of plastic crack tip opening displacement (CTOD, δp), as a crack driving force has given us the opportunity to predict fatigue crack growth (FCG) rate numerically, and, therefore, to develop parametric studies focused on the effect

A Numerical Analysis of Selected Elastic-Plastic Fracture Parameters for DEN(T) Plates under Plane Strain Conditions

open access: yesInternational Journal of Applied Mechanics and Engineering, 2017
This paper provides a numerical analysis of selected parameters of fracture mechanics for double-edge notched specimens in tension, DEN(T), under plane strain conditions. The analysis was performed using the elastic-plastic material model.

R-curve evaluation of pipeline girth welds using advanced measurement techniques [PDF]

open access: yes, 2014
A strain-based flaw assessment procedure is recommended for girth welded pipelines subjected to large deformations. To evaluate the allowable defect dimensions, the tearing resistance needs to be characterized.

Experimental and Numerical Analysis of Fracture in 41Cr4 Steel – Issues of the Stationary Cracks

open access: yesInternational Journal of Applied Mechanics and Engineering, 2018
This paper analyzes the process of fracture in 41Cr4 steel on the basis of experimental and numerical data obtained for non-propagating cracks. The author’s previous and latest experimental results were used to determine the apparent crack initiation ...
