Comparative Study on Optimal Stiffener Placement for Curvilinearly Stiffened Panels
Journal of Aircraft, 2011Recent studies have shown that curved stiffeners offer potential for structural tailoring of metallic panels. However, the optimal placement of the stiffener curves has remained a challenge, due to both the presence ofmultiple localminima in the design space as well as the associated CPU cost to solve the problem. This paper presents two new approaches

Vibrations of Orthogonally Stiffened Panels
Journal of Ship Research, 1978A general numerical method for the determination of natural frequencies and modes of vibration for orthogonally stiffened panels is presented. The panel is considered as an assembly of prismatic beams and plate strips rigidly connected along their longitudinal edges and transversely stiffened by beams of varying cross section.

Design and analysis of grid stiffened fuselage panel with curved stiffeners
AIP Conference Proceedings, 2018Designing and analyzing grid stiffened panel to understand the effect of stiffeners on stiffness of the panel is crucial in designing grid stiffened cylinder for fuselage application. Traditionally only straight stiffeners were used due to limited manufacturing capabilities and in recent years GSS with curved stiffeners have become a reality.

Cost Optimization of Stiffened Panels Using VICONOPT
AIAA Journal, 1998A novel and versatile optimum-cost design approach that embraces the ideology of concurrent engineering is described. The approach is incorporated into optimum-design software to permit the determination of the least-cost design for prismatic assemblies of laminated composite plates, which occur in advanced aerospace construction.

Stress-Intensity Factors of Stiffened Panels with Partially Cracked Stiffeners
1983Theory and numerical procedure are presented to determine the stress-intensity factors for a partially cracked typical stiffener and a partially cracked splice stiffener in a stiffened panel subjected to a uniaxial uniform remote stress normal to the crack.

AN ANALYSIS OF AN INTEGRALLY STIFFENED PANEL
1966Abstract : An investigation was made: (1) To design and test on integrally stiffened rectangular shear panel, (2) To develop analytical procedures for shear panels subjected to thermomechanical loading, and (3) To compare the analytical and experimental results to evaluate the accuracy of the analysis methods.
