Effect of Bow-Type Initial Imperfection On Reliability of Minimum- Weight Stiffened Structural Panels

چکیده

iii Summary Computations were performed to determine the eect of an overall bow-type initial imperfection on the reliability of structural panels under combined compression and shear loadings. A panel's reliability is the probability that it will perform its intended function|in this case, carry a given load without buckling or exceeding in-plane strain allowables. For a panel loaded in compression, a small initial bow can cause large bending stresses that reduce both the buckling load and the load at which strain allowables are exceeded; hence, the bow reduces the reliability of the panel. In this report, analytical studies on two stiened panels quantied that eect, which was found to be substantial.

Optimization of an Axially Compressed Ring and Stringer Stiffened Cylindrical Shell with a General Buckling Modal Imperfection

PANDA2, a computer program for the minimum-weight design of elastic perfect and imperfect stiffened cylindrical panels and shells under multiple sets of combined loads, is used to obtain optimum designs of uniformly axially compressed elastic internal T-ring and external T-stringer stiffened cylindrical shells with initial imperfections in the form of the general buckling mode. The optimum desi...

The Application of Reliability Methods in the Design of Stiffened Frp Composite Panels for Marine Vessels

The use of composite laminate materials has increased rapidly in recent years due to their excellent strength to weight ratio and resistance to corrosion. In the construction of marine vessels, stiffened plates are the most commonly used structural elements, forming the deck, bottom hull, side shells and bulkheads. This paper presents the use of a stochastic approach to the design of stiffened ...

Buckling of Stiffened Thin Walled Cylindrical Shells due to Global Shear

Thin walled cylindrical shells are important components of industrial structures such as liquid storage tanks, silos, etc. Shell buckling is usually a major failure mode of thin walled shells under extreme loads such as earthquakes. Longitudinal and radial stiffeners are generally used in order to increase buckling capacity of thin walled shells. During an earthquake, cylindrical shells may exp...
