Studies of the anisotropic yield condition

Journal of the Mechanics and Physics of Solids, 1969
Abstract A method of determining the subsequent yield condition is proposed on the basis of theoretical and experimental studies of the yield surfaces in the deviatoric plane. The yield surfaces as calculated by this method are compared with the results obtained by the biaxial testing of brass plate. A fairly good agreement is found between the two

Range of Yield Conditions in Ideal Plasticity

Journal of the Engineering Mechanics Division, 1961
Properties of ideal rigig plastic solids are used to define bounding yield conditions that remain valid when test results are available for only one stress state, such as simple tension or simple shear; use of maximum shear stress criterion of Tresca and new criterion designated as maximum reduced stress criterion enables best possible bounds to be ...

Tresca’s Yield Condition and the Rotating Disk

Journal of Applied Mechanics, 1983
The displacement field belonging to the elastic-plastic stress field in a rotating solid disk that can be found with the help of Tresca’s yield condition, in textbooks on plasticity, is discontinuous at the elastic-plastic interface. Tresca’s yield condition cannot be applied to this problem since its associated flow rule predicts a negative plastic ...

On the conditional decision procedure for high yield processes

Computers & Industrial Engineering, 2007
Cumulative Count of Conforming (CCC) items chart has shown to be an effective tool for monitoring high yield processes. However, this chart uses a single count value to determine whether a change in a process has occurred. This makes the chart relatively insensitive to process shifts. To improve the performance of the chart, values of the previous runs

Effect of microalgae storage conditions on methane yields

Environmental Science and Pollution Research, 2018
During the last decade, a lot of research has been focused on identifying the methane yields achievable when using microalgae biomass (fresh and pretreated) as a substrate in anaerobic digestion. Encountered differences are frequently attributed to the different microalgae strains (cell walls and macromolecular profiles) or the different metabolic ...

Plastic spin and evolution of an anisotropic yield condition

International Journal of Mechanical Sciences, 2000
Abstract Isotropic and anisotropic hardening will be combined with plastic spin in order to describe the microstructural behaviour of a polycrystalline metal in terms of continuum mechanics. In the present paper emphasis is given to the experimental procedure, based on previous work by Boehler and Koss and applied in order to verify that approach ...

Aelotropic Yield Condition

1970
In current literature ad hoc semi-emperial laws are widely used for transition problems in applied Mathematics, Physics and Engineering Sciences. It is particularly true of elastic-plastic deformation for which a number of yield conditions have been employed [8].

Yield conditions for layered composites

International Journal of Solids and Structures, 1981
Abstract The continuum elasto-plastic theory of layered composites is presented. The composite consists of two elasto-ideal plastic constituents. The associated flow rule is assumed to be valid for both constituents. The starting point of the presented considerations is an elastic state described by structural relations, i.e.

Visco-plastic flow and the tresca yield condition

Applied Scientific Research, 1970
This paper is concerned with a rigid visco-plastic solid which obeys the Tresca yield condition and an associated flow rule. Generalizations of both linear and nonlinear relationships between the rate of deformation and shearing stress in excess of the yield for simple shear flow are obtained from a complementary function.
