This paper discusses a general formulation of the material point method in the context of additive decomposition rate-independent plasticity. The process of generating the weak form shows that volume integration over deforming particles can be major source of error in the MPM method. Several useful ...
Then the paper analyzed the stress of the temporary connection, considering the materialplasticity. 最后,本文在考虑塑性变形的基础上,分析了梁段临时连接件的强度. 期刊摘选 Theplasticitystretching can ensures the flatness of the sloping wall. 斜壁的平面度是靠塑性拉伸保证的. ...
RESIST MATERIAL AND METHOD FOR FORMING AND REMOVING PATTERN OF THE MATERIAL PURPOSE:To obtain a resist material forming an easily removable resist and a pattern by using a specified Ge-contg. compd. and an optical acid generating agent. CONSTITUTION:A resist material is composed of a Ge-contg....
which extends its physical significance and lays down a good foundation for the application of the unified constitutive theory to the material analysis in more fields.This paper also introduces the unified constitutive model for metal materials and geo-materials.The numerical simulation indicates that ...
The recently developed methods of analyzing stress and strain distributions in the plane plastic flow of an ideally plastic material are applied to the problem of machining. It is shown that the idealized stress-strain relationship involves justifiable assumptions for this application. Analytical expressio...
摘要: A user-material subroutine has been written to incorporate single crystal plasticity in the fmite element program ABAQUS. The fmite-element formulation of elastic-plastic and viscoplastic single crystal deformation is reviewed in this paper. including versions for...
Cyclic plasticity and viscoplasticity of a new nickel-based superalloy have been studied using the Chaboche unified constitutive equations. The material parameters in the Chaboche model were evaluated by deriving the response sensitivities for typical load paths. This has facilitated the design of an ef...
Computational Examination of the Effect of Material Inhomogeneity on the Necking of Stent Struts Under Tensile Loading This study presents a computational investigation of tensile behavior and, in particular necking due to material inhomogeniety of cardiovascular stent stru...
