Uniaxial and biaxial ratchetting in piping materials—experiments and analysis [PDF]

International Journal of Pressure Vessels and Piping, 2004
Abstract The performance of the Chaboche kinematic hardening model has been evaluated in this paper to predict the ratchetting responses for a broad set of uniaxial and biaxial loading histories. The investigations have been performed with reference to both uniaxial and biaxial experimental data, viz.

Behaviour of composite solid propellant under biaxial tensile loading

Polymer Testing, 2023
Biaxial tensile tests were carried out on cruciform specimens of composite solid propellants. Digital Image Correlation (DIC) was used to measure the strain in the gage section. Experiments were conducted at displacement rates of 1, 50 and 1000 mm/min (Y

Influence of Biaxial Stress on Magnetic Behavior of Dual-Phase Steel—Experiments and Modeling [PDF]

IEEE Transactions on Magnetics, 2016
Online magnetic nondestructive evaluation (NDE) of dual-phase (DP) steels is made on bands submitted to high multiaxial stress. Extraction of microstructural information from the measurement requires separating the effect of stress and microstructure. Coupled magnetomechanical micromagnetic modeling is relevant for that purpose.

Prediction of fatigue crack initiation under biaxial loading [PDF]

Fracture and Structural Integrity, 2017
This investigation revisits biaxial fatigue experiments carried out with the nickel-based superalloy termed Waspaloy. Recently, yield criteria extended to multiaxial fatigue and stress based approaches were analysed and their performance to correlate the

Design and Analysis of a Quasi-Biaxial Solar Tracker

Energies
Inspired by C. Alexandru, to achieve a balance between tracking accuracy and equipment cost and between single-axis tracking brackets and dual-axis tracking brackets, a kind of quasi-biaxial solar tracker, whose approximate two-axis motions are driven by

Biaxial characterization of soft elastomers: Experiments and data-adaptive configurational forces for fracture

Journal of the Mechanics and Physics of Solids
Understanding the fracture mechanics of soft solids remains a fundamental challenge due to their complex, nonlinear responses under large deformations. While multiaxial loading is key to probing their mechanical behavior, the role of such loading in fracture processes is still poorly understood.

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

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.

Non-proportional tension-shear experiments in a biaxial test facility [PDF]

, 2006
This paper discusses the results obtained from experiments on DC06 mild steel with a biaxial test facility. The two presented tests are non-proportional tests consisting of a two stage strain path. First the samples are deformed in the tensile direction after which simple shear deformation is applied.

Experiments on Damage and Failure Behavior of Biaxially Loaded Specimens under Non-Proportional Load Paths

Physical Sciences Forum, 2022
This paper discusses new experiments with the X0-specimen taken from steel sheets and numerical simulations to investigate the influence of proportional and non-proportional loading on damage and failure processes in the moderate stress state regime. The

New Biaxial Specimens and Experiments to Characterize Sheet Metal Anisotropy and Damage

Physical Sciences Forum, 2022
The damage and failure behavior of anisotropic ductile metals depends on the material direction and on the stress state. Consequently, these effects have to be taken into account in material modeling and the corresponding numerical simulation, and also ...
