NUMERICAL/GRAPHICAL IMPLEMENTATION OF MAXIMUM STRAIN ENERGY DENSITY CRITERION

Transactions of the Canadian Society for Mechanical Engineering, 1992
In this paper a numerical/graphical method is developed to establish the initial angle of crack propagation and the associated fracture load for a crack in a mixed mode. This method incorporates the maximum dilatational strain energy density criterion (SED).

Material Anisotropy and Work Strain Characterized by Stationary Values of Strain Energy Density Function

1995
Stationary values of the strain energy density function are used to determine the relative position of the material symmetry axes and those of principal stress and strain. The minima and maxima would determine the directions of orthotropy for which the body would exhibit the stiffest or softest response.

Dynamic crack problems — strain energy density fracture theory

1991
The dynamic behavior of cracked systems prior and subsequent to the critical condition of mechanical instability has been the subject of many past discussions. This instability corresponds to the point at which a sudden change occurs in the creation of free surfaces.

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 ...

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.

Strain Energy Density Failure Criterion: Mixed-Mode Crack Growth

1993
So far, we have studied growth of a crack only for the case when the load is applied normal to the crack and such that the crack propagates in a self-similar manner. However, often the loads are not aligned to the orientation of the crack. In such cases, the crack-tip stress field is no longer governed by a single opening-mode stress intensity factor K

STRAIN ENERGY DENSITY APPLICATION IN MULTISCALE FATIGUE AND FRACTURE

2017
The monoscale consideration will not be applicable to multiscale materials, which motivates the formulation of multiscale fatigue model for metal materials. Scale segmentation involves multiple ranges. Strain energy density (SED) criterion could be a possible way to the solu- tion of multiscale fatigue and fracture.
