描述The present book provides a new method to estimate elastic-plastic strains via a series of linear elastic analyses. For a life prediction of structures subjected to variable loads, frequently encountered in mechanical and civil engineering, the cyclically accumulated deformation and the elastic plastic strain ranges are required. The Simplified Theory of Plastic Zones (STPZ) is a direct method which provides the estimates of these and all other mechanical quantities in the state of elastic and plastic shakedown. The STPZ is described in detail, with emphasis on the fact that not only scientists but engineers working in applied fields and advanced students are able to get an idea of the possibilities and limitations of the STPZ. Numerous illustrations and examples are provided to support the reader‘s understanding.

Introduction to the Behavior of Elastic-Plastic Solids and Structures,ture under force- or displacement-controlled load is illustrated. Some basics of plastic material behavior and approaches to their mathematical description by material models are then outlined, as far as they are of fundamental importance to strain rate independent plasticity in multiaxial stress st

STPZ at Monotonic Loading,STPZ, based on Zarka’s method, is easier to present initially for monotonic loading. A bilinear stress–strain curve, that is, linear kinematic hardening, is initially assumed as well as constant material data that do not change with temperature during thermal loading. After introducing a transformed

STPZ with Temperature-Dependent Material Data,n power plants. Temperature changes not only play the role of a load but also always bring about changes in the elastic and plastic material parameters. This chapter describes the effect of changes in the elastic material parameters, the yield stress, and the hardening modulus caused by a cyclic ani

Overlay Model,PZ can be expanded in Chap. 7 to account for nonlinear kinematic hardening, some preliminary work is required to provide a suitable material model. In this chapter a material model is considered with multilinear kinematic hardening, the overlay model of Besseling. In the literature this model is oft

STPZ at Multilinear Hardening,Plastic Zones (STPZ), on the basis of a uniaxial stress state. In this chapter, the STPZ is developed for multilinear kinematic hardening based on the overlay model for multiaxial stress states. In particular, information is provided on how the different plastic zones can be identified, how the init

STPZ with Temperature-Dependent Material Data,plified Theory of Plastic Zones (STPZ) are identified, together with the way this is done. Examples show that at least the temperature dependence of the yield strength can be successfully captured by the STPZ if the stress and strain extremes still occur at the load reversal points of the cyclic loading.
