A simplified strain energy density approach for multiaxial fatigue predictions

International Journal of Mechanical Sciences
Multiaxial fatigue is a critical challenge in industrial applications, where predicting fatigue life accurately is essential for components with complex geometries and out-of-phase loading conditions. These factors make traditional approaches economically demanding, necessitating simplified yet reliable methods.

Strain energy density failure criterion

1990
The selection of failure criteria for predicting the allowable load of structural components has historically been one of the problematic areas in design. The conventional approach often tends to penalize the structure in weight and size, if not economically.

The Strain Energy Density of Compressible, Rubber-Like Shells of Revolution

Journal of Applied Mechanics, 1996
An approach for the derivation of two-dimensional strain energy density functions of compressible, rubber-like shells of revolution which undergo axisymmetric, arbitrarily large rotations and strains including transverse normal and transverse shear strains is proposed. The proposed method is applied to polyurethane rubber, circular plates and numerical

A Strain Energy Density Function for Compressible Rubberlike Materials

Transactions of the Society of Rheology, 1976
A strain energy density function has been developed for compressible rubber-like materials. Its usefulness is demonstrated on hand of published data on the volume dilatation of natural rubber in simple tension.

A strain energy density criterion for the initiation of edge debonding

Theoretical and Applied Fracture Mechanics, 2015
Abstract Material or geometrical discontinuities within a structure induce a localized stress concentration which may initiate a crack leading to catastrophic failure in brittle materials. To assess crack initiation in the vicinity of a V-notch, a criterion based on the strain energy density (SED) averaged over a volume surrounding the notch tip is ...

On the minimization and maximization of the strain energy density in cortical bone tissue

Journal of Biomechanics, 1995
Universal minimization and maximization of the strain energy density, while possible in materials with cubic symmetry, is not possible for cortical long bone with its orthotropic material symmetry. Illustrating this point, it is shown that the stress state obtained when an axial load is applied along the long axis of a long bone at the midshaft is a ...

Decomposition of strain energy density in fiber reinforced composites

Composites, 1989
Abstract The elliptic paraboloid failure surface (EPFS) has been shown to constitute an ideal criterion for yielding and failure of fiber reinforced materials, whose predictions coincide with extensive experimental evidence in various fiber laminates.

A total strain energy density model of metal fatigue

Strength of Materials, 1995
In this paper a total cyclic strain energy density equal to the sum of plastic strain energy and tensile elastic strain energy densities is used as a damage parameter for metal fatigue. It is shown that the total cyclic strain energy density is a consistent damage parameter for low- and high-cycle fatigue in the conditions of both uniaxial and ...

Strain energy density and surface layer energy for blunt cracks or notches

1991
Although much effort has been spent in the past to develop failure theories, there is still considerable uncertainty involved in determining the strength of a material. A central problem facing the designer today is optimizing the use of the multivarious materials now known to him and available for application under various loading and environmental ...

Total Strain Energy Density as a Fatigue Damage Parameter

1989
It is shown that damage in uniaxial, multiaxial and load sequence effect can all be expressed in terms of an energy quantity termed as “total strain energy density”. It is the sum of the positive (tensile) elastic strain energy and plastic strain energy density.
