Abstract:

A nonlinear analysis of a 3D icosahedron frame was conducted using ABAQUS, under a compressive load in which collapse occurs. The frame was created in SolidWorks using the material properties of the 3D plastic building material VeroBlue. Two considerations were made the computational features of the frame, and the comparison between the experimental solution to the numerical solution. Two studies were also considered in this research The first study was a comparison between the seven-inch and the four-inch icosahedron model with identical weight to buoyancy ratios and the second study was a comparison between the seven-inch icosahedrons frame, with the experimental results of the data that was collected. The results of both studies are analyzed to compare against and verify the results of numerical computational model.
