From the ground up: Robotic Additive Manufacturing (RAM) of a structurally optimized earthen shell through computational design

When designing for structural performance, the geometry of the load-bearing elements is crucial for achieving the required stability. This is even more important in structural forms, such as shells and arches that are predominantly designed by their structural requirements. However, the typical design process starts with the design by the...

Calculation of vibration modes and resonance frequencies of the Northrop NF-5

The component mode technique is used to calculate resonance frequencies and vibration modes of the Northrop NF-5 structure. The results of the calculations are compared with those of a ground vibration test.
