ANSYS VISCOELASTIC MODELING

Submitted by saurabh_2110 on Thu, 08/12/2010 - 19:54

Hi,

I am trying to model a sheet of Poly Vinyl Butryl (PVB), which is a viscoelastic material in ANSYS. I have all the regular properties like elastic, shear and bulk modulus, poisson ratio, denstiy and damping factor. I also have a stress- strain curve of PVB. With all this data, is it possible for me to find the various constants in the viscoelastic models using ANSYS?

Thanks

Saurabh

I have a question regarding simple torsion of a circular shaft with a uniform cross section. Given a hollow circular shaft with inner radius R1 and outer radius R2, length L, shear modulus G, fixed-free boundary conditions and applied torque T about the central axis, the equation for the rotation angle at the end of the beam is

phi = T*L/(J*G)

where J = pi/4*(R2^4-R1^4)

I implement a program for fatigue crack growth in the XFEM.

But I have great difficulties to find material parameters used for PARIS- or FORMAN/METTU-equation.

Can anyone point me where this parameters could be released, for example for epoxy, polyurethane, 18CrNiMo7-6 and Aluminium.

I would very appriciate your response.

Hi all,

I am trying to replicate an analysis done in Abaqus by using LS Dyna. I've an input(inp) file of the abaqus model on which the analysis has been performed.

Mesh Less

My research field is Numerical methods in fluid dynamic. The method that we use named CDLS mesh-less method. It is based on MLS shape function and Least square equation discretization.

We decide to change our shape function from MLS to RPIM. We predict if this shape function couple with our method, we will reach better results in fluid dynamic problems. But we don't have any experience in using this kind of shape functions.

Now I am looking for a person who has experience in working with RPIM shape function for cooperation.
