摘要: One of the major difficulties in structural optimization at present is computational discrepancy between analysis capability and capability. This can be overcome, even reversed, by employing new optimality criteria (OC) methods which achieve correct optimal solution (i.e. Kuhn-Tucker point) while treating active stress constraints element level. means that their only limited number global (e.g. displacement or natural frequency) constraints. Since latter usually small for typical systems, these techniques increase our several orders magnitude.
