well I have not tried it yet myself. But seems if you want to change the bending stiffness you should change the D[4,4],D[4,5],D[4,6],D[5,5],D[5,6] and D[6,6] of the stiffness matrix

Well I think I found the answer. You can define your ABD matrix by defining the laminate properties in General Stifness Section. There you have a 6 by 6 matrix which is your ABD matrix (Section 29.6.6).

Hi, I am modelling Lamb waves propagation in a laminate structure. The excitation force is a tone-burst signal in out of plane direction which creates mostly bending modes. In order to take into account the bending modes, I used S4RS element which uses mindlin-reissner theory for transverse...

Thank you for the reply. Can you tell me how I can look at them please?

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...
