Finite element analysis of elastic-plastic solids under Vickers indentation: surface deformation

Finite element modeling has been used to study the development of surface deformation during indentation with a Vickers indenter. A wide range of materials with different elastic modulus and yield stresses are examined. Results show that in a pyramidal indentation process, for a perfectly plastic material, sinking-in during loading can change to pile-up in unloading. This phenomenon depends on ...

Constitutive Analysis of Large Elasto- Plastic Deformation Based on the Multiplicative Decomposition of Deformation Gradient

Abstract-By using Lee’s (1969. 1. Appf. hfech. 36, l-6) multiplicative decomposition of the deformation gradient into its elastic and plastic part of Hill and Rice’s (1973. SlAbf J. Appf. Math. U, 44S-461) constitutive framework. explicit and consistent constitutive analysis of large clastoplastic deformation is given. Both isotropic and anisotropic material behaviour is considered. so that som...

Numerical Analysis of Severe Plastic Deformation by High Pressure Torsion

High-pressure torsion (HPT) is a metal processing method in which the sample is subjected to a very high plastic shear deformation. This process can produce exceptional levels of grain refinement, and provides a corresponding improvement in mechanical properties. To investigate the stress and strain distribution due to HPT process finite element simulation were conducted to investigate effectiv...

Plastic deformation analysis in parallel tubular channel angular pressing (PTCAP)

Parallel tubular channel angular pressing (PTCAP) process is a novel recently developed severe plastic deformation technique for fabrication of ultrafine grained (UFG) metallic tubes. This new process consists of two half cycles and is affected by several parameters such as channel angles, deformation ratio and curvature angles. In this paper, the effects of these parameters on the plastic defo...

On the Corotational Beam Element Formulation in Large Deformation Analysis

This paper sheds more light on the co-rotational element formulation for beams with uniform cross-section. The co-rotational elements are commonly used in problems in which a structure undergoes a large deformation. In this study, the foregoing element obeys the Euler-Bernoulli beam assumptions. Unlike the formulations presented in the literature, in this paper, a number of local nodal coordina...
