Crack mesh

I am working for the FE model of cracked pipes. I use Hypermesh to mesh the model, but the element can not be set to the C3D20R type. I donnot kwon why it is. So I can use the C3D15. Then I can th following error message:

***NOTE: THE COORDINATES OF NODES WITHIN THE SAME CLUSTER ARE NOT IDENTICAL.  THIS IS THE CASE FOR NODES 22 1224

***ERROR: TRIANGLES, TETRAHEDRA, AND WEDGES MAY NOT BE USED IN A CONTOUR INTEGRAL REGION. ELEMENT 960 IS WITHIN A CONTOUR REGION

A question about electric displacement intensity factor of interacting cracks in piezoelectric materials

Submitted by Zhi Yan on
research

I am working on the problem of interacting cracks in piezoelectric materials. Due to the interaction of cracks, I found a non-intuitive phenomenon that the electric displacement intensity factor of the crack for some interacting profiles may be negative under some loading conditions (a tensile stress and an applied electric displacement). However, under the same loading conditions, the electric displacement intensity factor can never be negative for a single crack problem.

IS IT POSSIBLE TO DO A  RC CIRCUIT   COUPLED FINITE ELEMEN ANALYSIS USING ANSYS

I want to couple RC circuit  with one end to conducttor and other end to work peice .and study the electric feild intensity in conductor nd work peice..

 

THANks in advance

Vibration of a thermally stressed palte with various boundary conditions

Structural Dynamics and Aeroelasticity

Hi Friends,

I would like to have any suggestions or any comments related to a particular problem... There is a thin square cantilevered plate with temperature applied as boundary conditions along 10% of its edges. I would like to extract the first 5 natural frequencies and mode shapes for this problem. The issue is that I am not able to pick the right element (shell) from ANSYS to solve this problem.

cracking analysis OF a 3-points bended sandwich beam in the negative stressed area of the beam (above the neutral axis)

Submitted by Ilias I. Tourl… on

Hi,all

I'm looking for ideas-ways to model the above mentioned thema and solutions to overcome some obstacles. Here are some observations of mine:

1) Above the neutral axis of a bended beam the stress field is negative.Furthermore the traditional type of K factors estimation in Ansys is insufficient.The reason as i believe is that we haven't relative despacements of the crack nodes along  y(normal) axis.In contradiction we have shear desplacements.So i retrieve Ki nearly zero and Kii some noticable results.(using contact elements)

HI ,

I am Ashutosh..

i m a student of Mtech in cad/m from MNNIT, ALLAHABAD, INDIA.

I am working on my thesis for mtech which is to model erosive wear of materials under particle impact.

pls i need help on it as how can i model and simulate in abaqus/explicit.

 

hoping a reply..

regards

ashutosh
