Dear all !

I am trying to model Debonding Contact in Ansys Multiphysics, i also read Help to follow guide but i cant get any result because the Help is so general.

in my example, there two bars which is adhere with each other and be fixed at same site, the remaind sites is be forced !

If anybody knows how to model, pls guide me step by step

Thank so much for all help !

can i know how u applied pbc in your problem

pls can i get any input file how to apply perioidc boundary condition

how could you apply torque

how could you apply torque on the laminate elliptical tube?

Yes, *MODEL CHANGE,

villa7 — Thu, 28 Apr 2011 07:46:20 -0400

Yes, *MODEL CHANGE, ADD/REMOVE, type=...........

this will work to activate/deactivate the elements form current mesh, without changing mesh.

If you are doing ABAQUS/explicit, you can do element deletion based on some criteria.ou may use subroutine USDFLD for element deletion

Model Change

Hi,

I think the *Model Change functionality in ABAQUS could be a proper solution for your problem.

I want to model a advancing

R. Hasanpour — Tue, 26 Apr 2011 08:43:16 -0400

I want to model a advancing tunnel with ABAQUS. This
model will be run in two steps. My problem is modeling of excavating
tunnel after unblance the ground. For this modeling, first the tunnel
must be simulated without excavating it and would be subject to
unbalanced forces that is effecting from gravity. In next step, tunnel
would be excavated. For excavating tunnel it is essential that the
relating meshes to tunnel be removed. I could not remeve these meshes.
If anyone have the solutioun for this problem, please keep me informed.

Re: Rectangular Matrix in Matlab

N. Sukumar — Fri, 15 Apr 2011 02:04:25 -0400

I will rewrite your system as: Ax = b where A is a rectangular (non-square) matrix. You can find x in Matlab in couple of ways (at least): (1) Use the `slash` operator in Matlab, i.e., x = A\b which provides the `sparsest' x vector (most number of zeros) that satisfies Ax = b; or (2) Use the `pinv' function in Matlab (Morse-Penrose or pseudoinverse): x = pinv(A)*b which yields the solution x with minimum 2-norm.

you can do regression analysis... least squares fit

Harshit,

See the following derivation which answers your question, http://people.wallawalla.edu/~louie.yaw/otherfiles/overdetermined.pdf

I hope this is helpful.

Dear chiragzope,

I think you can use a gap contact element to simulate the contact between the beam and ground.
