Life Assessment of Corroded Wire for Prestressing

open access: yesMetals, 2023
The repair of structural elements for the prestressing of reinforced concrete is necessary when existing prestressing wires are damaged or after a certain period of time.

Failure Prediction of AISI 420 Martensitic Stainless Steel Using the Theory of Critical Distances [PDF]

open access: yesMaterials Research, 2021
This work aims to evaluate the capability of the theory of critical distances (TCD) to predict the static failure of U-notched AISI 420 martensitic stainless steel specimens with different geometric features under pure bending loading.

The application of the Theory of Critical Distances to nonhomogeneous materials

open access: yesFatigue & Fracture of Engineering Materials & Structures, 2023
AbstractThe Theory of Critical Distances (TCD) has undoubtedly represented a breakthrough in the brittle failure assessment of engineering materials containing defects, crack, or notches. The basic idea on which the simplest formulation of the TCD is based is to evaluate an effective stress at a characteristic distance from the tip of the defect/crack ...

KIc Determination of a 7075 T6 Aluminum Alloy by Critical Distances Theory and LEFM [PDF]

open access: yesMaterials Research, 2023
The Critical Distances Theory has been used in engineering field as a less expensive method to predict failures. Thus, this research aims to evaluate its methods in other materials, like the aluminum alloy 7075 T6, and notches. Two different notches were

The notch effect on fracture of polyurethane materials [PDF]

open access: yesFracture and Structural Integrity, 2014
This paper investigates the fracture properties and notch effect of PUR materials with four different densities. The asymmetric semi-circular bend specimen was adapted to perform mixed mode fracture toughness tests.

A relationship between tensile strength and mode I fracture toughness of rocks using the critical distance

open access: yesGeomechanics and Geophysics for Geo-Energy and Geo-Resources, 2023
Correlations between material parameters are useful because they provide a first estimation of unknown parameters. Here, the correlation between the tensile strength and the mode I fracture toughness of rocks is studied.

Theory of critical distances: A discussion on concepts and applications

open access: yesProceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2021
Theory of Critical Distances (TCD) collects several methods adopted in failure prediction of components provided with stress concentration features. The idea of evaluating stress effect in a zone rather than in a single point was proposed decades ago but, only thanks to relatively recent works, TCD concepts showed to be a successful extension of Linear

On the multiaxial fatigue assessment of complex three-dimensional stress concentrators [PDF]

open access: yes, 2014
This paper assesses and quantifies the detrimental effects of complex tri-dimensional notches subjected to uniaxial and multiaxial fatigue loading. A number of experimental results taken from the technical literature and generated by testing specimens ...

HebCrit: a new dimension of critical race theory [PDF]

open access: yes, 2020
I believe that it is essential to identify a new facet of Critical Race Theory that specifically addresses the needs of the Jewish people. Often overlooked and ignored in multicultural, diversity, and ethnic studies, Jews continue to face specific ...

Towards a critical realist theory of labour market information [PDF]

open access: yes, 2022
Despite the importance of Labour Market Information (LMI) to career practice, there is a surprising lack of theory that focuses on LMI and how it supports career guidance.
