sweep mesh of a dome in ANSYS

dome

I am dealing with a partial sphere dome in ANSYS, I created the volume by extruding half of an arch area along the axis at the dome center. I am using SOLID65 elements. The problem I am facing now is how to properly sweep mesh the whole volume ( actually, there are four 90 degree partial sphere together after the extrude of the area), because if I simply sweep the volume, the elements around the top center of the sphere will cause element shape warning in the static analysis.

Dose anyone have any idea about how to deal with the mesh around the center? 

 

Instrumented Indentation, It's More Than Hardness

Submitted by NANOVEA on

As the validity of Instrumented Indentation continues to expand throughout all materials research, many throughout the community are still unclear as to what exactly can be achieved. Although advances in technology will continue to grow the list of capabilities of Instrumented Indentation, we will review a list of what can be expected as of now. But first lets quickly review how Instrumented Indentation works.

Damage modeling with UMAT

Submitted by Panos Efthymiadis on
UMAT

Dear all,

      I am using a Abaqus modeller with fortran subroutines. I have written a UMAT subroutine and now want to apply some damage initiation-evolution criteria. But I get the following error: a damage initiation property was used with a user material.

I wanted to apply the criteria externally from the subroutine.. How can I go through with this problem? I tried different criteria (stress and strain based) to check if it is a matter of the output variables... No result..
