Analyzing the structural integrity of ferritic steel structures subjected to large temperature variations requires the collection of the fracture toughness (KJc) of ferritic steels in the ductile-to-brittle transition region. Consequently, predicting

A spreadsheet-based simplified and direct toughness scaling method to predict the temperature dependence of fracture toughness J c in the ductile-to-brittle transition temperature region is proposed. This method uses fracture toughness test data and

In this paper, a ferritic CrMo steel SCM440 which satisfies the prerequisites of ASTM E1921 master curve (MC), but which this MC failed to characterize its fracture toughness KJc temperature dependence is introduced. The material was tested at four t

The fracture toughness Jc of the material in the ductile to brittle transition temperature (DBTT) region shows test specimen thickness (TST) effect and temperature dependence, and apparently increases when compressive residual stress is applied. In t

In this paper, a new method for scaling the crack tip stress distribution under small scale yielding condition was proposed and named as T-scaling method. This method enables to identify the different stress distributions for materials with different

This paper examined whether the modified Ritchie-Knott-Rice (RKR) failure criterion can be applied to examine the feasibility of miniaturized Charpy type SE(B) specimens of thickness-to-width ratio B/W=1. The modified RKR failure criterion considered

The improvement in the fracture toughness Jc of a material in the ductile-to-brittle transition temperature region due to compressive residual stress (CRS) was considered in this study. A straightforward fracture prediction was performed for a specim

This work was motivated by the fact that although fracture toughness of a material in the ductile-to-brittle transition temperature region Jc exhibits the test specimen thickness (TST) effect on Jc, frequently described as Jc∝(TST)-1/2, experiences
