Buckling of plate strip subjected to localised corrosion—a stochastic model

The paper deals with the effects of localised corrosion on the buckling load of a plate strip. A stochastic model of the problem is suggested and intact plate thickness, modulus of elasticity, corrosion loss of weight and position of corroded area of a chosen extent are assumed as basic random variables. The design values and the first three statistical moments of the critical loads are calculated and the results are referred to the upper bound of probability distribution of corrosion loss of weight. The numerical study employs data from the recent experimental research [Bull. Tech. Univ. Istanbul 47(1994) 423] and a relationship between stochastic and experimental results is drawn.
