Crack creation problem - FRANC3D with ABAQUS

Thu, 2008-08-21 01:51 - satyasrinivas
curved crack

I am trying to develop a model in ABAQUS and perform crack analysis using FRANC3D. I am having a problem right at the beginning.

I am able to create the model in ABAQUS and write the .inp file. I open this file in FRANC3D and am trying to insert a curved crack. I repeat a 'curved crack'. The crack is not planar. When I try to define the crack front using 'user defined points', the software is approximating all the points I enter to a best-fit 'plane'. So it is generating a planar crack when i wanta curved crack.

ABAQUS HEX MESHING - HELP NEEDED

Wed, 2008-07-09 12:32 - satyasrinivas
research

Hi,

 I am trying to mesh a solid in CAE using HEX elements. For some reason, I am getting an error message saying that the element topology is not right for the geometry.

 I eventually want to do crack analysis and so hex or wedge elements are essential for my model. Could anyone please help me and let me know if there is a way to go around the problem and get a hex mesh on the solid. I am attaching the .jpeg file of the geometry of the solid I want to HEX mesh.

 

Thanks a lot in advance
