Biaxial Loading Experiments for Determining Interfacial Fracture Toughness

Journal of Applied Mechanics, 1991
The paper establishes the range of in-plane fracture mode mixtures and contact zone sizes that can be obtained from an edge-cracked bimaterial strip under biaxial applied displacements. The development of a suitable loading device for and the application of crack opening interferometry to interfacial crack initiation experiments is described. The crack

Biaxial Deformation Experiments Over Multiple Strain Regimes

1997
Dominant inelastic deformation processes of polycrystalline metals in the infinitesimal strain regime are different than those at larger strains. Within the infinitesimal strain regime, dislocation/dislocation interactions and the nucleation and evolution of small-scale dislocation structures such as dislocation cells dominate the strain-hardening ...

Validation of a Constitutive Material Model with Anisothermal Uniaxial and Biaxial Experiments*

Materials Testing, 2009
Abstract The dynamic behaviour of steam turbine components is currently a key issue in terms of the discontinuity in the power supply from regenerative energy systems like wind-mills. These systems call for a combined and flexible use of conventional steam power plants.

Experiments and numerical simulations on damage behavior of biaxially loaded specimen

PAMM, 2014
AbstractThe paper deals with the effect of stress state on damage and failure behavior of isotropic ductile metals. In the continuum damage model the damage behavior of ductile metals is adequately described by a generalized damage condition and an anisotropic damage rule. The damage criterion is based on series of uniaxial experiments with differently

Biaxial stretching of heat‐softened plastic sheets: Experiments and results

Polymer Engineering & Science, 1975
AbstractA second‐generation apparatus was built and used to inflate heat‐softened plastic sheets to shapes from hemispheres to large spheroidal bubbles. Three sheet materials, polystyrene, high‐impact polystyrene, and cellulose acetate butyrate, were successfully formed beyond the hemispherical shape at temperatures somewhat below industrial levels ...

An anisotropic continuum damage model for concrete based on biaxial experiments

PAMM, 2018
AbstractThe paper deals with an anisotropic continuum damage model to describe the brittle damage and fracture behavior of plain concrete. Due to the stress state dependence of damage and fracture, multiaxial experiments have to be analyzed to make sure the model is able to simulate the observed physical phenomena.

Four-sublattice model of a biaxial antiferromagnet and its comparison with experiment

Soviet Journal of Low Temperature Physics, 1985
Utilizing a four-sublattice model that takes account of the Dzyaloshinskii interaction and the tensor nature of the g-factor for spectroscopic splitting, we consider the ground states and frequency–field dependences of the antiferromagnetic resonance of a biaxial antiferromagnet at T = 0 in a magnetic field parallel to the “easy” antiferromagnetism ...

Biaxial cyclic deformation of an epoxy resin: Experiments and constitutive modeling

Journal of Materials Science, 2005
Biaxial (proportional and non-proportional) cyclic tests were conducted on thin-walled tubular specimens to investigate deformation behavior of an epoxy resin, Epon 826/Epi-Cure Curing Agent 9551. The focus was placed on the biaxial stress-strain response and their dependency on the load control mode, stress or strain range and loading path ...

Biaxial deformation of rubber-like solids: comparison of theory and experiment

Journal of Physics D: Applied Physics, 1979
The strain-energy function of a rubber-like solid may be characterised by stress-deformation data from experimental tests in which two principal stretches of a homogeneously deformed specimen are varied independently. In the context of the continuum theory of finite elastic deformations, a framework is described within which such experimental results ...

Experience in Data Acquisition and Reduction for a Biaxial Mechanical Testing Program

1976
The inadequacy of uniaxial mechanical testing data as a basis for predicting multiaxial deformation and fracture is well known. For optimal biaxial tests, computer control of simultaneous variation of loadings using hydraulic power under closed loop servocontrol is essential.
