Finite element modeling of porous titanium
The porous microstructures of metallic foams cause microscopic stress and strain localization under deformation which reduces the damage tolerance and therefore limits application of the materials. In this paper, the deformation of a relatively low porosity porous titanium is examined using two-dimensional (2D) plane strain and three-dimensional (3D) finite element models to identify the accura...
متن کاملFinite element modeling of 3 D turning of titanium
The finite element modeling and experimental validation of 3D turning of grade two commercially pure titanium are presented. The Third Wave AdvantEdge machining simulation software is applied for the finite element modeling. Machining experiments are conducted. The measured cutting forces and chip thickness are compared to finite element modeling results with good agreement. The effects of cutt...
متن کاملFinite element modeling of the human head under baton impact
Purpose: This research will try to predict damage probability and calculate the main stress resulted from baton impacts by finite element (FE) modeling of the human head considering skull texture, brain and cerebrospinal fluid.Materials and Methods: A three dimensional FE model of the skull-brain complex was constructed for simulating the baton impact. The FE analysis was carried out using ANSY...
متن کاملThe Finite Element Method for Porous Materials
To reduce the noise and vibration perturbations, it is beneficial to use the dissipative properties of poroelastic materials. These materials are generally not used alone, but rather inserted in composite mechanical assemblies made of elastic structures, poroelastic materials and air insertions. If these structures are assemblies of layers of materials, they are called multilayer complexes. If ...
متن کاملFinite Element Modeling of Heat and Moisture Transfer in Porous Material
Abstract—This paper presents a two-dimensional model to study the heat and moisture transfer through porous building materials. Dynamic and static coupled models of heat and moisture transfer in porous material under low temperature are presented and the coupled models together with variable initial and boundary conditions have been considered in an analytical way and using the finite element m...
