Distortional strain energy density criterion: the

Engineering Fracture Mechanics, 1991
Abstract The complete formulation of the distortional strain energy density criterion is presented. The criterion minimizes the distortional strain energy density component to predict the propagation direction. It further postulates that propagation will commence when this minimum reaches the material critical distortional strain energy density ...

The Strain-Energy Density of Compressible, Rubber-Like Axishells

Journal of Applied Mechanics, 1987
A recent method for deriving, by descent from three dimensions, strain-energy densities in a first-approximation, large-strain theory of incompressible, elastically isotropic shells of revolution undergoing torsionless, axisymmetric deformation (axishells) is adapted to axishells made of compressible material. Application is made to the Blatz-Ko strain-

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.

Femoral bone mineral density distribution is dominantly regulated by strain energy density in remodeling

Bio-Medical Materials and Engineering, 2000
BACKGROUND: It is well known that there is a relationship between bone strength and the forces that are daily applied to the bone. However, bone is a highly heterogeneous material and it is still not clear how mechanical variables regulate the distribution of bone mass in a femur.

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.

Local Strain Energy Density Concept

2013
The local strain energy density (SED) approach is elaborated for strength assessments in respect of brittle fracture and high-cycle fatigue. Pointed and rounded (blunt) V-notches subjected to tensile loading (mode 1) are primarily considered, occasionally extended to multiaxial conditions (mode 3, mixed mode 1 and 2).

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 ...

The Strain Energy Densities of Hexagonal and Tetragonal Epitaxial Media

Japanese Journal of Applied Physics, 1995
Motivated by the burgeoning interest in the epitaxial growth of hexagonal and tetragonal semiconductors, we report expressions for the strain energy density for the high symmetry directions in these crystal systems. In addition, we have calculated the behaviour of the strain energy density as a function of epilayer surface normal orientation for the ...

Lattice structure: Scaling of strain related energy density

Theoretical and Applied Fracture Mechanics, 2015
Abstract The strain energy density (SED) was used as the criterion to characterize stable and unstable crack growth in the fracture mechanics of linear and non-linear constitutive relations. It applies equally well for continuum mechanics problems in general. It is free from the restrictions of theories that implicate linear superposition. The energy
