An anisotropic tertiary creep damage constitutive model for anisotropic materials

When an anisotropic material is subject to creep conditions and a complex state of stress, an anisotropic creep damage behavior is observed. Previous research has focused on the anisotropic creep damage behavior of isotropic materials but few constitutive models have been developed for anisotropic creeping solids. This paper describes the development of a new anisotropic tertiary creep damage c...

A Theoretical Study of Wall Ironing for Anisotropic Workharden Materials

Finite element simulation of pyroplastic deformation, anisotropic shrinkage and heterogeneous densification for ceramic materials during liquid phase sintering process

Pyroplastic deformation is a distortion of the ceramic shape during the sintering process. It occurs because the flow of the vitreous phase at high temperature and the applied stress due to the weight of the product during sintering process. The aim of this paper deals with describing a numerical-experimental method to evaluate the pyroplastic deformation, to predict the anisotropic shrinkage a...

Computer Simulation of 3-D Liquid Transport in Fibrous Materials

Liquid movement in 3-D fibrous materials is studied in this article by means of Monte Carlo simulation based on the Ising model with so-called Kawasaki kinetics. Computer simulation algorithms are then developed in accordance with the standard liquid wicking rate tests from both EDANA and INDA, and the simulation results provide information of liquid wicked into computer-generated fiber assembl...
