Scrap-iron and steel pipe against aliens
grabcad
In Round 2, scrap iron and steel pipes face off against aliens. The analysis involves comparing simple parts (rods and tubes) with complex ones (aliens), using the same material and terminals for fixing and loading. A plane bending study is conducted, calculating the ratio of maximum load to weight as a measure of excellence. However, the finite element method (FEA) incorrectly simulates complex parts, indicating design flaws in the parts, particularly in Autodesk Inventor. STEP format files for all parts are uploaded, with a commitment to solving this issue. Assistance is sought for identifying issues 1) improper combinations of solids in complex cases in aliens, potentially due to interpolation errors at Voronoi cell boundaries, and 2) defects caused by non-exact standard joint sets (t-pipe) in aliens, requiring custom part geometry or joint sets.
