The strain energy density criterion

1984
It is a common experience that breakage of a material under load can be preceded either by large or small deformation depending on the temperature, rate of loading and other variables present. The former occurs over a relatively long time period and may be associated with yielding or plastic flow.

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 rubber-like shells

International Journal of Solids and Structures, 1985
Under the assumption that the state of a shell is described by the change in the first and second fundamental forms of its midsurface from an initially elastic isotropic state, an approximate strain energy density is derived, first using strictly two-dimensional arguments and then by descent from three dimensions assuming incompressibility.

Fracture initiation under gross yielding: Strain energy density criterion

Engineering Fracture Mechanics, 1983
Abstract The damage of metal alloys at the continuum level can be described by a combined process of yielding and fracture. Yielding is generally associated with excessive distortion and fracture with excessive dilatation. With the increased use of low strength alloys, gross yielding can often precede the initiation of macrocracking.

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.

Local Strain Energy Density and Fatigue Strength of Welded Joints

2008
Weld bead geometry cannot, by its nature, be precisely defined. Parameters such as bead shape and toe radius vary from joint to joint even in well-controlled manufacturing operations (Taylor et al., [1]). In the notch stress intensity approach to the fatigue assessment of welded joints, the weld toe is modelled as a sharp V-notch and local stress ...

Experimental fracture mechanics: strain energy density criterion

1991
The objective of this chapter is to impart a better understanding of the mutual dependence of theory and experiment in fracture mechanics. An experiment cannot be considered successful unless the results are interpreted within the framework of some preconceived concept and/or theoretical prediction.

Strain energy density of carbon-black-loaded rubber vulcanizates

Journal of Physics D: Applied Physics, 2000
The strain energy density behaviour is studied at room temperature, for 100 phr (parts per 100 parts of rubber by weight) FEF carbon-black-loaded styrene-butadiene rubber (SBR), natural rubber (NR), butadiene-acryle nitrial rubber (NBR), butyl rubber (IIR) and butadiene rubber (BR).

Total strain energy density parameter for fatigue analysis

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2000
AbstractIn the paper a new damage parameter‐total strain energy density for fatigue analysis has been examined. The parameter can be applied to both Masing and non‐Masing material description. The relationships of the proposed damage parameters for both types of material description have been shown.

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.
