Application of the equivalent material concept to ductile failure prediction of blunt V-notches encountering moderate-scale yielding

International Journal of Damage Mechanics, 2016
The equivalent material concept, proposed originally by the first author for predicting tensile load-carrying capacity of ductile metallic materials weakened by V-notches, was employed together with two well-known brittle fracture criteria, namely the point-stress and the mean-stress criteria, to estimate theoretically the tensile load-carrying ...

THE CONCEPT OF EQUIVALENCE OF CLICHES AND STAMPS (BASED ON THE MATERIAL OF RUSSIAN AND KOREAN OFFICIAL BUSINESS LANGUAGE)

The American Journal of Social Science and Education Innovations, 2023
In this paper we are interested in translation at the level of a word combination. A word combination can represent a semantic unity both at the level of language. The most striking example of such a translation is the translation of idiomatic or stable (phraseological) word combinations. The process of translation of official business texts is closely

Fracture study in notched ductile polymeric plates subjected to mixed mode I/II loading: Application of equivalent material concept

European Journal of Mechanics - A/Solids, 2018
Abstract Fracture of a ductile polymeric material containing U-notches is studied both experimentally and theoretically under mixed mode I/II loading conditions. Rectangular plates containing a central bean-shaped slit with two U-shaped ends are utilized for conducting fracture tests.

On the Ability of the Equivalent Material Concept in Predicting Ductile Failure of U-Notches under Moderate- and Large-Scale Yielding Conditions

Physical Mesomechanics, 2015
In the present research, first, the equivalent material concept (EMC), proposed originally by the first author to equate a ductile material with a virtual brittle material, was utilized in conjunction with two stress-based brittle fracture criteria, namely the point-stress (PS) and the mean-stress (MS) criteria, to develop two combined failure criteria

Estimation of tensile load-bearing capacity of ductile metallic materials weakened by a V-notch: The equivalent material concept

Materials Science and Engineering: A, 2012
Abstract Ductile commercial steel was equated from the viewpoint of strain energy density with a virtual brittle material of the same elastic modulus by using a novel concept, called the equivalent material concept (EMC). By determining the ultimate tensile strength of the virtual material and also, by assuming that the values of the plane–strain ...

Tensile failure in blunt V-notched ductile members: A new formulation of the Equivalent Material Concept

Engineering Fracture Mechanics, 2017
Abstract First, the Equivalent Material Concept (EMC), originally proposed by the author in 2012, is newly formulated in a way the effects of the plastic region ahead of the notch tip prior to the formation of crack at the notch tip on tensile strength of the equivalent material are taken into consideration.

On combination of the equivalent material concept and J‐integral criterion for ductile failure prediction of U‐notches subjected to tension

Fatigue & Fracture of Engineering Materials & Structures, 2018
AbstractThe aim of the present research is to check the capability of the equivalent material concept (EMC) combined with the J‐integral failure criterion, called EMC‐J criterion, in predicting the load‐carrying capacity (LCC) of U‐notched ductile aluminium plates subjected to tension by considering the 2 moderate and large‐scale yielding regimes.

Crack growth onset in thin aluminum sheets under mixed mode I/II loading: A new form of the Equivalent Material Concept

Thin-Walled Structures, 2019
Abstract Ductile failure of diagonally loaded square plate (DLSP) samples, created from Al 6061-T6 and Al 7075-T6 alloys with small thickness weakened by central cracks, is assessed theoretically and experimentally under combined in-plane loading. To provide different combinations of mode I and mode II loadings in the tests on DLSP, various crack ...

Mixed mode І/ІІ fracture prediction of blunt V-notched nanocomposite specimens with nonlinear behavior by means of the Equivalent Material Concept

Composites Part B: Engineering, 2018
Abstract Mixed mode I/II fracture of ductile nanocomposite components containing blunt V-notches was studied both experimentally and theoretically. Fracture tests were conducted on the rectangular plates containing a central rhombic hole with four blunt V-shaped corners, which were fabricated for two different notch angles of 30° and 60° and various ...
