Rotation DOF have no meaning for 3D solid elements. These DOF exist in 1D and 2D elements as a mean to simplify the small dimensions. You can see them as the way of connecting the mesh nodes to the shallow structure section orientation.
ABAQUS has a shell to solid feature but it is rather...
Hello, not all formats are readable. It depends on what you want to use. If you want the mesh and the restitution basis, you will need the binary results file output.
We develop a toolbox (SDT-FEMLink) that implements such read and much more, and will let you work in MATLAB with a proper FEA...
Damping is not additive, and not linked to stiffness or mass in general. You will thus not be able to easily setup a guess without assumptions.
That said, if you are working with loss factors in structural dynamics, you can use the Modal Strain Energy assumption. It states that the synthesized...
