NONLINEAR FINITE ELEMENT MODELING OF CRYSTALLINE MICROSTRUCTURAL PROPERTIES WITH APPLICATION TO ALUMINUM ALLOYS FOR MODERN ARMORS

Simulation and modeling of friction welding of stainless steel to aluminum alloy using finite element method and artificial neural network

Aluminum to stainless steel joints are broadly used in industries in order to reduce fuel consumption. While fusion welding is not a suitable method to join these metals. solid state welding, like friction welding (FW), is an effective way to this process. However, risk of intermetallic compounds (IMCs) formation is probable in these welds. In previews investigations formation of FeAl3, Fe2Al5 ...

Microstructural Scale Effects on Fatigue of Aluminum Alloys

ABSRACT A comparative study of the surface microstructural changes after fatigue in an ultrafine grained and coarse grained aluminum alloy was performed using orientation imaging microscopy (OIM). The fraction of low angle boundaries with misorientation less than 2.5 ̊ increased for both the coarse and ultrafine grained alloys. A consistent decrease in the fraction of low angle boundaries, with ...

Application of symbolic finite element tools to nonlinear hyperelasticity

The present paper addresses the use of high level languages, symbolic mathematical tools and code generation in an implementation of the finite element method, using a nonlinear hyperelasticity equation as example. Advantages of the software development method that will be demonstrated include closeness to the mathematics, enabling high human efficiency with easy to use high level languages, wh...
