O niektórych uogólnieniach twierdzeń nośności granicznej dla ośrodka Cosseratów

This paper presents the generalizations of limit analysis and shake-down theorems of Melan and Koiter to the case of Cosserat media. Moreover, the variational principle of Mura-Lee, Ziegler's conclusion from the first and second laws of thermodynamics and Drucker's postulate have been generalized. The problems discussed in the paper are based on Lippmann's theory of plastic flow of Cosserat media.
