Evaluation of the Admissible Sizes of Faulty Fusion in Cellular Thin-Walled Elements

摘要

We determine the stress-strain states near technological cracklike faulty fusions in cell elements and deduce the relation for the stress intensity factor K (I) near a cracklike faulty fusion and determine its critical length. It is shown that the faulty fusions with lengths not greater than a half thickness of the wall do not affect the strength of cellular products.
