I have developed a model in HyperMesh for Radioss which involves the impact between a truss-like structure (modeled using 3D elements after importing CAD geometry) and a rigid body impactor at a given velocity, but am looking for a bit more information regarding the theory involved in simulating this scenario.
Based on the Radioss Theory Manual, I am led to believe that the solver does indeed take buckling failure of the struts of the structure into account, even though it is not necessarily a direct "buckling problem." However, I am looking for some confirmation of this or some additional material so that I could read to better understand the theory utilized since it is important that the buckling failure of the struts is considered during the impact event in my model.
Please let me know if you need any further information about the model or any clarification.
Thank you in advance for any guidance you are able to provide.
