Evaluation of the equivalent material concept in mixed mode I/III fracture estimation of V-notched Al7075-T6 plates

Engineering Fracture Mechanics, 2020
Abstract For the first time, performance of the Equivalent Material Concept (EMC) in investigating fracture of V-notched ductile members subjected to mixed tension/out-of-plane shear loading, so-called mixed mode I/III loading, is examined. On the basis of EMC, a ductile material can be equated with a virtual brittle material in order to avoid ...

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 ...

Application of the equivalent material concept to the study of the ductile failure due to U-notches

International Journal of Pressure Vessels and Piping, 2019
Abstract This paper studies the applicability of the Equivalent Material Concept to the fracture of elastoplastic materials due to the presence of U-notches. This approach consists of simplifying the study of an elastoplastic material by assuming linear elastic behaviour.

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.

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.

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 ...

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

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.

On the use of the Equivalent Material Concept to predict tensile load-bearing capacity of ductile steel bolts containing V-shaped threads

Engineering Fracture Mechanics, 2013
Abstract The equivalent material concept (EMC), proposed recently by the author for predicting the tensile load-bearing capacity of ductile metallic materials weakened by V-notches, was utilized together with the mean stress (MS) criterion to estimate the experimentally obtained maximum loads that several ductile steel bolts with V-shaped threads can

Notch ductile failure with significant strain‐hardening: The modified equivalent material concept

Fatigue & Fracture of Engineering Materials & Structures, 2018
AbstractThe equivalent material concept (EMC) assumes that the ductile material has a valid K‐based fracture toughness (KIc or Kc). For ductile materials with significant strain‐hardening, no valid KIc or Kc is determined by the standard experiments and, hence, EMC seems null.
