Strain-energy density function for rubberlike materials

Journal of the Mechanics and Physics of Solids, 1979
Abstract T he strain-energy density function surface for the rubber tested by L. R.G. T reloak (1944a) is determined from bis stress-strain data. The data were given for the three pure homogeneous strain paths of simple elongation, pure shear, and equi-biaxial extension of a thin sheet.

Strain energy density – a molecular appraisal

Journal of the Chinese Institute of Engineers, 2004
Abstract The interaction potential between two clusters simulating the crack tip on the lattice level is derived in this work. Employing molecules as the building blocks and the Lennard‐Jones potential as the Green's function, the close‐form solution shows that the 1/r‐type of singularity is an intrinsic behavior of the energy field when mutual ...

Strain energy density function and uniform strain hypothesis for arterial mechanics

Journal of Biomechanics, 1987
Stress distribution through the wall thickness of the canine carotid artery was analyzed on the basis of the uniform strain hypothesis in which the wall circumferential strain was assumed to be constant over the wall cross-section under physiological loading condition.

Strain energy density of VO2-based microactuators

Sensors and Actuators A: Physical, 2013
Abstract The strain, stress and strain energy density of a vanadium dioxide (VO 2 )-based microactuator were obtained from experimental curvature measurements as a function of temperature. The study revealed fully reversible strain and stress changes of up to −0.32% and −510 MPa, respectively, and a maximum strain energy density of approximately 8.1 ×

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

The strain energy density function

1986
Failure prediction deals with the forecast of conditions involving material damage that tends to decrease the capability of structural members to support load. With the added influence of moisture and temperature, the situation becomes more complicated because their interaction with mechanical stresses must also be considered. This concern arises since

Strain energy density failure criterion

International Journal of Solids and Structures, 2001
Starting from Clausius-Duhem inequality in which the free energy depends on elastic and plastic strains, temperature, damage tensor and plastic internal variables, the author derives an intrinsic general dissipative energy density leading to a failure criterion described by the critical value of elastic strain energy density.

Pseudo Strain Energy Density-Based Structural Damage Identification

Key Engineering Materials, 2009
In this paper, a new time-domain method for detecting structural local damage has been developed, which is based on the measured strain signals. The “pseudo strain energy density (PSED)” is defined and used to build two major damage indexes, the “average pseudo strain energy density” (APSED) and the “average pseudo strain energy density changing rate” (
