Abaqus: Composite layup

[shubbad]

I want to create a 3D shell part.I am modelling two shell part as a single part, both the shell part has different thickness and different material property. I tried composite Layup, but I'm unable to do. I'm attaching the image how the geometry will be. Please guide.

Composite layup is meant for cases when multiple layers (of different thickness, material and orientation) are needed through the thickness. If what you need is just a spatial variation of the properties, make a partition and apply different sections to those two faces.

I will make it more clear through Images. I have made part like this but when I am sketching like this these will not act as single component. If I want to calculate the forces or moment at the bottom , it will give different values for both, but if i can make it as a single component then if it will act as a single component. How I can make it ? Please guide.

If you want to connect those parts, you can either use the Merge/Cut Instances tool or apply tie constraints. Of course, in both cases, the segments have to be touching so that the nodes on both sides are connected. Otherwise, those will be separate parts and a frequency analysis will show that they can move independently.
