Web9 de jul. de 2024 · Two approaches were developed: First, structural cores were produced with AM, over-laminated with CFRP, and co-cured in the autoclave. Second, a functional hull is produced with AM, filled with a temperature- and pressure-resistant material, and over-laminated with CFRP.

Web1 de mar. de 2001 · In a remarkable paper, Michell (1904) defined the requirements for least-weight structures to support a given set of loads. He showed that for minimum weight, all of the structural elements must be strained, under the action of the external forces, by exactly the same strain magnitude, ε, in either simple tension or pure compression. Web9 de mar. de 2016 · Michell’s optimal frame structures (Michell 1904) have been intensively used as benchmark problems in topology optimization.
