Manipulating ABD formulation
Manipulating ABD formulation
(OP)
I am working on a transient simulation of a laminate. I use the composite layups feature to use laminate theory for characteristics of my shell elements. Here you should define the properties of a ply so that Abaqus uses laminate theory to create the ABD matrices. My question is, Is there anyway I can get access to the matrices and manipulate them? Or define the ABD matrices instead of defining the ply properties?
My aim is to decrease the D (the bending stiffness matrix) for bunch of elements in my structure.

1. Use the A/CAE Plugin. Search in the DS Knowledge Base for answer QA00000008126 to find the plugin and instructions.
2. Use a Shell General Section (integration before analysis) and request model data output when creating the job. Then it is written into .dat during the datacheck.
3. Use *Element Matrix Output. Optionally add *File Format to get ASCII data.
