Application of Elasto-Plastic Analysis to Tunnelling
2001Some applications are presented of the elasto-plastic and visco-plastic stress analysis to tunnelling problems. First, the closed form solution is recalled of the so-called “characteristic line” of a circular opening, which is frequently adopted for a simplified evaluation of the load acting on the lining of deep tunnels.

The subject of elasto-plastic bending of beams, columns, frames and other complex structures has generated a considerable volume of specialised literature, the review of which is outside the scope of this book. However, to gain an appreciation of the range of topics covered and the ways in which they are approached, we shall consider a selection of ...

Elasto-Plastic Finite Element Simulations
2014The continuum mechanics basics for plasticity, i.e. the yield condition, the flow rule, the hardening law, and the elasto-plastic modulus, for the one-dimensional rod will be used to describe the elasto-plastic behavior for monotonic and cyclic loading.

Theory and Numerics of Elasto-plasticity
2014In case of ductile materials like steel for which this theory is developed it is assumed that the behaviour is linearly elastic until reaching are certain stress, the yield strength σ y . It is described by Hooke’s law, thus by Young’s modulus E and Poisson’s ratio ν. This holds strictly speaking for materials with a distinct yield strength like in Fig.

On finite deformation elasto-plasticity
International Journal of Solids and Structures, 1982Lee (1969) has proposed a theory based on the decomposition of the total deformation gradient to an elastic and plastic part, and from it has concluded that the additive decomposition of the strain rates holds only approximately. Lubarda and Lee (1981) have declared that Lee's 'exact finite-deformation kinematics shows the almost universal assumption ...

Elasto-Plastic Material Behavior
2015This chapter introduces first the basic equations of plasticity theory. The yield condition, the flow rule, and the hardening rule are introduced. After deriving and presenting these equations for the one-dimensional stress and strain state, the equations are generalized for a three-dimensional state in the scope of the von Mises and Tresca yield ...

Finite-strain elasto-plasticity
2000In this chapter, the infinitesimal theory of elasto-plasticity of Chap. 12 is generalized to finite strains. Two formulations are presented. The first one is based on a multiplicative decomposition of the deformation gradient into elastic and plastic parts and on hyperelastic stress-strain relations.
