VICONOPT swMATH ID: 10341 Software Authors: Butler, Richard; Liu, Wenli Description: Optimisation of stiffened panels using finite strip models. The key features of the finite strip buckling analysis program VICONOPT are described. A bi-level strategy, for the efficient optimum design of composite stiffened panels is also presented. Panel level optimization finds a minimum weight cross-sectional geometry based on a substitution of equivalent orthotropic plates for laminated plates. Optimization at the laminate level finds stacking sequences satisfying laminate design rules using either manual selection or a genetic algorithm. VICONOPT models are validated with ABAQUS finite element models, and with experimental compressive testing of two blade-stiffened panels. The buckling and postbuckling behaviour of the two panels, with initial buckling in the stiffeners and skin, respectively, is investigated in a high load and high strain range. The bi-level strategy is evaluated by design of a Z-stiffened example, which has been manufactured and tested, and also by design of a wing cover panel which is subject to compression and lateral pressure. The optimum wing panel, considering a variety of stiffener shapes, is 17 Homepage: http://arc.aiaa.org/doi/abs/10.2514/3.10820?journalCode=aiaaj Related Software: PANDA; ABAQUS; CONMIN; ABAQUS/Standard; BIANCA; PFVIBAT; FASOR; ANSYS; ADS; STAGS Cited in: 19 Publications all top 5 Cited by 25 Authors 9 Williams, Frederic W. 3 Butler, Richard J. 3 Watson, Andrew J. 2 Liu, Wenli 2 Rhead, Andrew T. 1 Anderson, Melvin S. 1 Bushnell, David H. 1 Casimir, J.
