This paper presents the uniqueness and existence conditions for a rate-independent plasticity model for single crystals under a general stress state. The model is based on multiple slips on three-dimensional slip systems. The uniqueness condition for the plastic slips in a single crystal with nonline...
Since the generalized variational principle of elasto-plastic mechanics was developed,it has been a problem for scientists and researchers to incorporate these variational principles with plastic flow theory of more standard forms.In this paper the latest developments in elasto-plastic constitutive theory ...
Gradient plasticity theories which are used to describe size effects require nonstandard boundary conditions. We believe that the role of these boundary co... R,H,J,... - 《Modelling & Simulation in Materials Science & Engineering》 被引量: 45发表: 2007年 On the uniqueness and sensitivity is...
Some Comments on the Endochronic Theory of PlasticityViscoplastic propertiesPlastic deformationMathematical modelsStress strain relationsPoisson ratioOne dimensionalTwo endochronic theories of plasticity advanced by Valanis in 1971 and 1978 are discussed critically. It is concluded that the first of these ...
Photos of the work: Books On Books Collection. If you live where red kites thrive, you will see them most often singly, in pairs or threes. If you are lucky, you may see as many as eight or ten at a time. Near Harewood House in West Yorkshire where red kites were reintroduced in...

The two models are compared and analyzed, which is also the uniqueness and innovation of this study. The simulations results of the two models are in good agreement with the creep tests. 展开 关键词: Oxidation Creep Crystal plasticity theory Initial pre-oxidation damage model Two-phase model Ni...
In the last decades, fastening systems have become an essential part of the construction industry. Post-installed mechanical anchors are frequently used in concrete members to connect them with other load bearing structural members, or to attach applianc
In theory, on the basis of its structural analysis, the modal, fatigue strength and life of the hub were simulated using the finite element method, and the lightweight design of the hub was verified. This method provides a useful reference for the lightweight design of automotive parts. In ...
