inclusions

Hi all

 

I am phd student and working on aluminium alloy 2214. i wanted to know if anyone here has experience of FE modelling of inclusions present in alloys by Ansys? i have characterized my material n i know inclusion distribution n size. can anyone help me in this regard?

 

 

Merci en avance

A Geometric Theory of Thermal Stresses

Submitted by arash_yavari on

Thermal stresses
Geometric elasticity

In this paper we formulate a geometric theory of thermal stresses.

Given a temperature distribution, we associate a Riemannian

material manifold to the body, with a metric that explicitly

depends on the temperature distribution. A change of temperature

corresponds to a change of the material metric. In this sense, a

temperature change is a concrete example of the so-called

referential evolutions. We also make a concrete connection between

our geometric point of view and the multiplicative decomposition

Fatigue
experimental data

Can anyone help point me to publicly-available fatigue or fracture test data? I am interested in obtaining a variety of data for statistical processing. It seems many authors have used the data collected by Virkler and Hillberry which seems to be widely used, but I have not found raw data for their tests so far; is this data available somewhere for me to use? Any help is very appreciated.

Moving Heat Source in Gmaw process

Dear Sir/Madam,

       

i m quite new wd the ansys and was trying to simulate a problem of moving heat source in GMAW and has to move wd some Heat flux on  the plate .how could i model heat distribution of the GMAW and how could i move it wd some velocity.. 

i hope i m clear,plz help me out.

 Thank You,

Welcome to the forum! Discussion topics were suggested initially as follow:

Metal foams, cell deformation (bending, buckling, plasticity and fracture), constitutive stress-strain behaviour of cellular materials, energy absorption, hypervelocity impact, shock wave behaviour, 1D shock modelling, shock attenuation, shock enhancement, Material Point Method (MPM) simulation and microscopic tomography experimental observation;

and later were extended to many related:
