Three-dimensional effects at plate crack tips. (English. Abridged French version) Zbl 0748.73009

Summary: The three-dimensional boundary layer in the vicinity of plate crack tips is under investigation. Far from the tips, the correcting term to the solution of the generalized plane stress problem is equal to a special linear combination of the weight functions. Two-dimensional models are discussed.
