Work Bounding Functions for Plastic Materials

Journal of Applied Mechanics, 1976
The minimum work and maximum complementary work potentials for both time-independent and time-dependent plasticity are reconsidered from the viewpoint of internal variable theories. It is shown that the minimum work and maximum complementary work can be bounded in a simple and direct manner. The bounds provide the minimum work and maximum complementary

Plastic work in the peeling of work hardening foils

Journal of Adhesion Science and Technology, 1997
The plastic work consumed by the flexible metallic foil during a peel test can contribute significantly to the measured load. It is thus important to be able to quantify it in order be able to make inferences about the adhesion at the interface. Several models have been previously proposed which allow the calculation of the plastic work, based on the ...

Plastic Working of Metals

Journal of Fluids Engineering, 1956
Abstract The material presented in this paper is in itself a brief review of the art of plastic working of metals which has been compiled in order to stimulate discussion of the subject at the first annual meeting following the establishing of the ASME Research Subcommittee on the Plastic Working of Metals.

Compressive behavior of worked plastics

Journal of Applied Polymer Science, 1974
AbstractThe effect of temperature and loading history on the compressive stress–strain properties of two plastics is described. Polypropylene and nylon cylindrical specimens were reduced in height by 20%, 40%, 60%, and 80%, at room temperature and 25°F below the melt point and at two different deformation rates.

A work criterion for plastic collapse

International Journal of Pressure Vessels and Piping, 2003
A new criterion for evaluating limit and plastic loads in pressure vessel design by analysis is presented. The proposed criterion is based on the plastic work dissipated in the structure as loading progresses and may be used for structures subject to a single load or a combination of multiple loads.

The crack initiation and plastic work

Engineering Fracture Mechanics, 1988
Abstract The effect of the ratio a/W on the values of δ i , and i in a structural steel has been studied by measuring the crack opening displacement and J- integral at initiation of crack growth in three-point bend specimens with shallow and deep notches and by three-dimensional finite element method analysis.

One plasticity model for problems of plastic metal working

Journal of Applied Mechanics and Technical Physics, 2008
Scalar and tensor models of plastic flow of metals extending plasticity theory are considered over a wide range of temperatures and strain rates. Equations are derived using the physico-phenomenological approach based on modern concepts and methods of the physics and mechanics of plastic deformation.
