On plastic deformation and fatigue under multiaxial loading

Nuclear Engineering and Design, 1996
This paper presents an experimental and theoretical investigation of deformation and fatigue behaviour under multiaxial random loading. The inelastic stress-strain response under complex loading paths has been predicted using an incremental plasticity model, which incorporates a memory rule to account for the variable-amplitude and non-proportional ...

Failure of cellular foams under multiaxial loading

Composites Part A: Applied Science and Manufacturing, 2002
Abstract A thorough investigation of the mechanical behavior of a closed-cell cellular foam (Divinycell) under multiaxial stress conditions was undertaken. Two types of Divinycell, H100 and H250, with densities of 100 and 250 kg/m3, respectively, were investigated.

Multiaxial Fatigue Under Variable Amplitude Loads

Journal of Engineering Materials and Technology, 1999
Multiaxial fatigue under variable amplitude loading is investigated using Kandil et al.’s parameter, rainflow cycle counting on the shear strain history, and the Miner-Palmgren damage rule. Fatigue data are obtained on tubular specimens of S45C steel under proportional and nonproportional tension-torsion loading.

Buckling Tests of Cylindrical Composite Shells in Multiaxial Loading

AIAA SCITECH 2025 Forum
Thin-walled cylindrical composite shells are prone to buckling failure in a variety of load cases. The number of influencing factors and comparably small amount of test data on combined load cases, which regularly occur in application, pose a major design challenge.

A Comparison of Creep Theories for Multiaxial Loading of Polyethylene

Transactions of the Society of Rheology, 1971
Several creep theories are investigated for multiaxial loading of high-density polyethylene, a slightly cross-linked polymer demonstrating a nonlinear stress-strain-time relationship. Among the theories considered are nonlinear viscoelastic models, isochronous stress-strain diagrams employing a hyperbolic sine relationship, and multiple integral ...

Damage evolution rule for multiaxial variable loading

1998
The damage accumulated within the material element is associated with the physical plane and predicted by the contact stress or strain rule. For singular stress or strains regimes a nonlocal failure or damage rule is used. The application to both monotonic and variable loading is provided.

Studies of Webbings Under Multiaxial Dynamic Loading

Textile Research Journal, 1998
The aim of the project is to study the bending fatigue properties of one kind of webbing under multiaxial dynamic loading in order to determine its maximum dura bility and longest useful lifetime. The study uses a dynamic fatiguing test machine, and the varying test parameters are camber radius and pulley diameter, the safety factor of the webbing ...

Fatigue life of structural elements in multiaxial loading

Russian Engineering Research, 2010
The fatigue life of structural elements in multiaxial loading may be assessed on the basis of the balance of fatigue strength, taking account of the change in stress-strain state in multiaxial and uniaxial loading.

Durability Analysis Under Complex Multiaxial Loading

SAE Technical Paper Series, 1987
<div class="htmlview paragraph">Components subjected to multichannel service load inputs require time-based loads both for testing and analysis. The paper discusses the techniques available for time-based history characterization and outlines a new Peak-Time history compression procedure.

Plastic flow under multiaxial cyclic loading

Experimental Mechanics, 1986
An experimental study of the inelastic behavior of annealed aluminum alloy 6061-T6 tubular specimens subjected to combined axial and torsional stress cycles is presented. Particular attention is paid to the question of how plastic strain is developed and how the yield surface moves along the 90-deg out-of-phase stress cycle.
