Round 2. Scrap-iron and steel pipe against aliens · 模型 308302
A second attempt to calculate the stresses in complex parts (aliens). Details: see the first round https://grabcad.com/library/scrap-iron-and-steel-pipe-against-aliens-1 See the third round: https://grabcad.com/library/round-3-scrap-iron-and-steel-pipe-against-aliens-1 I tried to use standard software for converting mesh to the surface. Workflow Alien 4. Rhino(Grasshopper->Lattice)->Mesh->AutodeskEnableMesh for Inventor v.1.03->Solid part (One section of the structure)->Assembly->FEA Alien 5. Not really Alien. Inventor only->FEA Alien 6. Rhino(Grasshopper->Lattice)->Mesh->InStep v2.3.->Solid part ( One section of the structure)->Assembly Strength analysis suggest to make everyone who wants (I have not enough time). The results are shown in the final table. Surprisingly, wins the traditional pipe. This does not mean that the simple shapes better. To optimize the complicated parts need to spend more efforts and time. I think that efficient parts ( in terms of the load/weight ratio) will be demand, especially in the aerospace industry. Сonclusion 1. I was wrong: the details can not be compared with the same diameter.Lattice aliens are losing the traditional details. A more logical to compare the weight for a given strength. 2. Transformation meshes in the surface does not work well. Either dramatically increases file size, or significantly distorted by the geometry of the object.
