Contributor Kassapoglou, C. (mentor) Faculty Aerospace Engineering Department Aerospace Structures and Materials Date 2016-07-04 Abstract Localized buckles can occur in crashes when compressive stresses are dominant. However, due to their local appearance, they might be overlooked by a finite element analysis, meaning that local failure due to buckling will not be predicted. Methods to analytically assess the onset of such buckles are readily available. However, an off-the-shelf solution to predict the behaviour of them after the initial onset is not on hand. Therefore, an analytical method is developed that can predict the behaviour of a buckle after its onset, even in complex multiaxial states of stress that may be expected in crash scenarios. The strain over the buckle is captured as well, meaning that material failure can be predicted using existing material failure models.
