Hi to all,
I was wondering if there is any built-in expression for calculating the second moment of area (area moment of inertia) using the Expression Tool. I’ve tried searching with keywords such as "inertia", "second moment", and "moment of inertia", but haven’t been able to find a suitable expression so far.
Any guidance on how to access or define such an expression would be greatly appreciated.
Best regards, Mirhan

In the Structural Mechanics Module, you have the Beam Cross Section interface. There, all relevant types of cross section properties, including the quantities you are looking for, can be computed for arbitrary shapes.
