I would like to make a career in Finite Element MEthod with concentration on topics like XFEM,Mesh-free methods--

However, I am yet to mmake a start.To give you my background I ahve a good knowledge of subject of Strength of Materials,Linear Finite Element Analyis-including coding structrial analysis involving beam elements,plate elements,plane stress and plane strain elements-all linear FE.

I have good programming skills-C,VB,MathCAD and know basis of C++ well

I havee just undergone a course on Linear Algebra through the MIT opencourseware.

Hi,

Can anybody throw some light on the wear coupling characteristics between SS347 and 17-4 PH, as well as between Phosphor Bronze and 17-4 PH Steel?

It will be helpful if you could refer to some literature where I can learn about Wear Coupling Characteristics...

Thank You,

Navanee

Hello to all,

I use the meshless Galerkin method for 3D simulation of plate movement. This method requires the volume integration over a test domain. Could somebody help me with the volume integration? I wonder if there are standard or open source algorithms that can be used for this problem.

I would appriciate any help.

Hi,

I have to model adhesive with viscoplastic beahviour in Ansys. But before that, I need to find its parameters through experiments.

Do you think that Anand model can be successfully applied for adhesives? Or anyone can suggest some better model?

I can find ample of litearture for solder alloys where Anand model has been validated well but there are very few literatures available for constitutive relation for adhesives.

I will really appreciate if someone can provide me the link to good references regarding this.

Thanks

I am trying to model a rubber impregnated fabric as rebar in Abaqus Standard. It seems that the rebar is only good in uniaxial tension load and it causes convergence problem in bending and compression loading. The fabric and rubber matrix has a compressive strength and that is critical to the model that I am analyzing. What would be a good approach to include compression on fabric rebar? The compressive strength of fabric matrix should be an order of magnitude lower than the tensile strength but I do not have a test data in compressive loading.

Hello,

I'm trying to model indentation of a viscoelastic material in Abaqus.

I have (1) stress-relaxation curves for the material and (2) force-displacement curves for the material from a real indentation experiment.

From this I can readily calculate the elastic modulus (infinite) and the elastic modulus (instantaneous) for the material.

I'd like to fit a Prony series based on this data that I can enter into Abaqus to model the material.

How would I go about fitting the Prony series from the force-displacement and stress-relaxation curves?
