Dynamic Vibration Analysis of a cantilever beam and its effect on neighbouring beams by using ansys

Submitted by madhava on

Hi,

As a first step in the vibration analysis of the beam, I have modelled 2 rectangular cross section 3D beam and am doing the modal analysis in ansys, but the problem is there is no interaction happening of the 2 beams(ie i have defined the contact and target parameters to the' nodes of the 2 faces of the beam facing each other',by using cintaca170, 174), the beam behave as if there is no neighbouring beam.

Can anyone suggest something.

Does anyone have the paper “Equivalent inclusion method for steady state heat conduction in composites”?

Hellow everyone, Ican not find the paperin the titil, Does anyone have it ? My email address is "041858 [at] gmail.com".

Thanks very much.

Two UMATS in one Subroutine

Submitted by ABAqirl on

Dear All,

I have the problem. i created very simple example with two elements. To one element i prescribed the behaviour Mat1, to another element Mat2. I tried to use two different UMATS for this two elements.

I created Subroutine Myname.f, in which i use CMNAME if (CNMAME.EQ.'MAT1) THEN

CALl UMAT_1()

ELSE IF (CMNAME.EQ.'MAT2) THEN

CALL UMAT_2()

END IF

Then i put two UMATS in the same SUBROUTINES ,

But as a result the program gives MISTAKE , it says that The UMAT doesn't exist

What is the mistake?

Looking for an equivalent indentation modulus for composite

Dear all (and Prof. Ciavarella, if you can see this),

I am looking for an equivalent indentation modulus for orthotropic composite materials in a contact problem. Does anybody has any reference or equation to get the value?
