| contents | <p>Fail-safe design often leads to oversized structures as the design must be able to behave properly for the different accidental<br>situations that could undergo throughout their lifespan. The existing research about structural optimization applied to<br>fail-safe design does not contemplate the idea of having accidental situations with different probabilities of occurrence.<br>This means that the structure must satisfy the design constraints in the damaged structure regardless of whether one<br>accidental situation is much more likely than another. The objective of this research is to formulate a new optimization<br>strategy to get fail-safe structures with minimum weight taking into account the available data about the probability of<br>occurrence associated to each partial collapse. A multi-model probabilistic optimization problem is defined and applied to<br>two structures: a 2D truss structure with stress constraints as well as the tail section of an aircraft fuselage with stress and<br>buckling constraints.</p> |
