Multi-axial fatigue numerical crack propagation in cruciform specimens

Fracture and Structural Integrity, 2019
Two cracks, initiated from the opposite tips of a central notch inclined by 45°, were considered in cruciform specimens made of Ti6246. A static load was applied to a cruciform arm while a cyclic load was applied along the other arm.

Introducing a novel sheet test specimen for biaxial stretching under uniaxial loading

Advances in Industrial and Manufacturing Engineering
This paper introduces a novel sheet test specimen that plastically deforms under biaxial stretching when subjected to uniaxial loading in conventional testing machines.

Determination of instability of a DP 980 steel sheet under different stress states based on experiment and theoretical models

MATEC Web of Conferences, 2016
It is generally accepted that the formability of sheet metal is limited by the onset of instability which can be described by forming limit diagram (FLD) in ε1-ε2 space.

Multi-axial fatigue numerical crack propagation in cruciform specimens

Procedia Structural Integrity, 2018
Abstract Two cracks, initiated from the opposite tips of a 45° inclined central notch, were considered in cruciform specimens made of Ti6246. A static load was applied along an arm of the cruciform specimen together with an alternating load (R=-1) applied along the other arm.

Biaxial loading effects on large -scale cruciform specimens

, 2015
To address the influence of biaxial stress effects on fracture, experimental work has been reported in theliterature on cruciform specimens containing defects. For example, some large-scale tests were carried outfor the US Nuclear Regulatory Commission at the Oak Ridge National Laboratory in the 1990s,concluding that biaxial loading in the form of an ...

A Thermo-Mechanical Coupled Gradient Damage Model for Heterogeneous Rocks Based on the Weibull Distribution

Energies
This study develops a thermo-mechanical damage (TMD) model for predicting damage evolution in heterogeneous rock materials after heat treatment. The TMD model employs a Weibull distribution to characterize the spatial heterogeneity of the mechanical ...

SIMULATION OF EFFECTS OF GRAIN DISTRIBUTION MORPHOLOGY ON FATIGUE BEHAVIOR OF SHORT CRACKS AT WELD TOE (MT)

Jixie qiangdu, 2023
Fatigue cracks of the welded structure often initiate at the weld toe. Under the complex metallurgical-physical process, the grain sizes and their distribution morphology at the weld toe site show obvious variation.

Towards biaxial fatigue experiments of elastomers using square and cruciform geometries in planar tension conditions

Polymer Testing
Soft materials such as natural rubber, hydrogels, and biological tissues have anisotropic properties and are subject to cyclic biaxial loading during their service lives.
