Strain-softening analysis of concrete structures

Computers & Structures, 1989
The numerical model of concrete should account for tension and compression softening phenomena observed experimentally. The finite element model presented here allows multidirectional strain-softening to take place within the element. The effective use of strain-softening models depends on solution routines employed with the model.

Strain-Induced Softening of Certain Eutectics

Physical Review Letters, 1980
It is suggested that the considerable softening of the lattice of certain superconducting eutectic mixtures, and the accompanying increase in transition temperature are the result of large unrelieved strains that weaken the effective spring constant between neighboring atoms.

The nature of directional strain softening

Scripta Metallurgica, 1983
Softening transients are sometimes seen in metals following a change in direction of straining. One example of such softening is that occuring upon a strain direction reversal, for example, during uniaxial reversed cyclic deformation at a large strain amplitude.

Strain‐softening of brittle geologic materials

International Journal for Numerical and Analytical Methods in Geomechanics, 1978
AbstractStability equations for a strain‐softening system are derived from expressions describing the energy variation in a variable stiffness stiff testing machine and a brittle rock specimen. A normal strain‐softening expression and a shear strain‐softening expression are derived to predict the stability of laboratory tests on brittle rocks, which ...

Strain softening in an epoxy resin

Journal of Materials Science, 1982
Post-yield behaviour, particularly strain softening, has been studied here for an epoxy resin to examine the effects of postcuring and plasticization by water and a non-volatile diluent dibutylphtalate. The significance of necking was examined by conducting compression tests (at room temperature) as well as tensile tests.

A discussion of strain-softening in concrete

International Journal of Fracture, 2004
The question of whether concrete strain-softening is a real material property is discussed here. The discussion is given from both the physical and the analytical point of view. New evaluations of the actual nature of strain-softening are added to those existing in literature.

Directional strain softening in ferritic steel

Acta Metallurgica, 1987
Abstract Unidirectional cold working induces directionality of structure and properties. This directionality affects yielding and flow when the material comes into another deformation mode. In particular, when the strain is reversed a transient region of strain softening occurs.

Flexural behavior of strain-softening solids

International Journal of Solids and Structures, 1989
Abstract The flexural behavior of a beam is investigated in an attempt to establish a correlation between the tensile and bending properties of strain-softening solids. Given the complete uniaxial stress—strain relations, including the post-peak tension-softening portion, it is possible to predict the flexural behavior in moment—curvature and load ...
