Study on Damage Tolerance Behavior of Integrally Stiffened Panel and Conventional Stiffened Panel
The damage tolerance behavior of integrally and conventional stiffened panel is investigated based on the fracture mechanics and finite element analysis. The load bearing capability and crack growth characteristic of both types of the stiffened panels having same configuration subjected to distributed tensile load is examined in this paper. A fourteen-stringer stiffened panel is analyzed for a ...
متن کاملOptimum Buckling Design of Composite Stiffened Panels Using Ant Colony Algorithm
Optimal design of laminated composite stiffened panels of symmetric and balanced layup with different number of T-shape stiffeners is investigated and presented. The stiffened panels are simply supported and subjected to uniform biaxial compressive load. In the optimization for the maximum buckling load without weight penalty, the panel skin and the stiffened laminate stacking sequence, thickne...
متن کاملDesign optimization of stiffened composite panels with buckling and damage tolerance constraints
The design of stiffened, composite wing panels must satisfy a range of requirements related to performance, economy and safety. In particular, the design must be damage tolerant to satisfy a number of different performance requirements for various states of damage. To obtain an optimum configuration that satisfies these requirements simultaneously, optimization code PANOPT was extended with a m...
متن کاملBuckling strength of uniaxially compressed orthogonally stiffened plates
The bucking strength calculation includes the determination of global buckling strength, the effective plate width and the torsional buckling strength of open section stiffeners. In each calculation the classic strength formula should be modified considering the effect of initial imperfections and residual welding stresses. The calculation method of Det Norske Veritas design rules and the Euroc...
متن کاملNeural Prediction of Buckling Capacity of Stiffened Cylindrical Shells
Estimation of the nonlinear buckling capacity of thin walled shells is one of the most important aspects of structural mechanics. In this study the axial buckling load of 132 stiffened shells were numerically calculated. The applicability of artificial neural networks (ANN) in predicting the buckling capacity of vertically stiffened shells was studied. To this end feed forward (FF) multi-layer ...
