LIMIT ANALYSIS FOR STRUCTURES WITH FLAWS

An analysis is described which aims at computing the limit load for an imperfect structure containing internal defects or flaws. A criterion is proposed for evaluation of the ultimate stress at a certain admissible crack size. This approach incorporates some plastic properties of the material and it requires an experimental determination of the critical stress intensity factor for the given range of the crack length. A safety factor defined with regard to catastrophic crack propagation is introduced in addition to standard safety factors used in the design. Finally, some numerical examples are given to illustrate the procedures for evaluation of an admissible crack size and for estimating the corresponding safety factors.
