Abstract: This paper obtains a closed-form general solution to the two-surface plasticity theory for linear stress paths. The simple two-surface model is discussed first. It is shown that according to ...

Abstract: This paper presents a general formulation of the nonlinear and linear analysis of wire ropes. In the formulation, wires, strands, and wire ropes are all considered as a kind of identical ...

Abstract: This paper presents a simple direct method for the straightforward determination of steady-state solutions in shakedown analysis of structures subjected to sustained and cyclic loadings. The method is based upon the ...

Abstract: This paper first points out that an evolution rule of the yield center without a motion component in the plastic strain rate direction leads to ratchetting, while an evolution rule with such a component motion leads to ...

Abstract: Several hardening models are investigated in this paper to examine how they predict material behavior under closed-loop loading paths. The linear Prager's kinematic hardening rule and a new kinematic hardening model proposed ...

Abstract: This paper investigates how the two‐surface plasticity theory predicts material behavior under nonproportional loading conditions. Closed‐form solutions are found for a thin‐walled tube subjected to combined internal ...

Abstract: The present paper proposes two rules to develop a new kinematic hardening model. The first rule regulates the movement of the yield surface. It states that during loading, the yield center moves such that the kinematic ...

Abstract: This paper discusses the elastic‐plastic response of thick‐walled hollow spheres subjected to internal and external pressures, and radial temperature gradient. The kinematic hardening rule is used in the analysis, and ...

Abstract: This paper presents a detailed investigation of the shakedown behavior of thick‐walled hollow spheres subjected to cyclic temperature and sustained internal and external pressures. It is found that under sustained and ...

Abstract: Piping branch junctions and nozzle attachments to main pressure vessels are common engineering components used in the power, oil and gas, and shipbuilding industries amongst others. These components ...
