Hi Khar Chun Lee ,

Personally I have used connector elements. Similar to truss elements they transmit force axially. I have found it easier implement these types of elements. They have an added advantage of allowing for tabular data so that you can model nonlinear properties. The downside of using connectors vs truss elements is that connectors don't have cross-sectional area, they are essentially springs.

If you want to use truss elements you will need to create a separate part for each ligament. The part would be a line, and when it is placed in the assembly the end points of the line will be need to have the tie boundary condition to a node on the corresponding facet joints. Alternatively you can merge your assembly into a single part and create wires directly on your merged part.

If you are using connector elements, go into the:

Interaction module

Connector > Geometry > Create Wire Feature and select two end points.

Create a connector section in:

Connector > Section > Create

I use the following settings

Connection Category - Basic

Transnational Type - Axial

Rotational Type - None

Good luck,

Aaron

Hi Aaron Gee

I have tried using the truss elements by merging the parts and create wires directly on the merged part. However, when i run analysis, the results seem to be the same as the part without truss element. Is is anything wrong with my modelling?

Hi,

I am also trying to do the same thing for my studies. The link below may be beneficial:
