Modification of the Formula of Papkovich-F?ppl for a Compressed Thin-Walled Rod with an Open Profile

[摘要] The article is about thin-walled rods of open cross-section compressed by multiparameter load. It is known that the critical multiparameter load factor can be calculated by the formula of Papkovich-Föppl. In this article, the formula is modified so that it takes into account the change in cross-section dimensions of the rod. The modified formula can be used to optimize such dimensions.
