A mathemati.al model i. presented, and numeri.al experi.ents are performed to descri.e the mechani.s of the slow mov.ment of a pi.eli.e. The problem reducti.n algori.hm to one-di.ensi.nal formulati.n i. offered. Results of numeri.al experi.ent for the model problem are adduced. The proposed mathemati.al model i. found to adequately descri.e the dynami.s of known phenomena of pi.es. The cross-secti.ns of the extended curv.li.ear thi.-walled pi.eli.e are numeri.ally demonstrated to experi.nce warpi.g, whi.h has experi.ental confi.mati.n i. the li.erature.
