Írásunkban két végén befogott, vékony (100 μm-nél vékonyabb) lemezek egyirányú húzás hatására bekövetkező ráncosodását vizsgáljuk. Az irodalomban széles körben használt, infinitezimális nyúlásokon alapuló Kármán Tódor-féle nagy lehajlású, vékony lemezek elmélete a nyújtás egy kritikus értéke felett a ráncos mintázat stabilitását jósolja, függetlenül a további nyújtás mértékétől. Numerikus szimulációk alapján a ráncos mintázat korlátlan stabilitása nem igazolható akkor, ha az elméleti levezetés (összhangban a terheléssel) véges nyúlásokat is megenged. Ez utóbbi modellben a triviális, síkbeli megoldás egy második bifurkációs pontban visszanyeri stabilitását. Jelen írás célja ezen előrejelzés kísérleti igazolása polipropilén szalagok elmozdulás-vezérelt nyújtásával. A kísérletekből meghatározott elágazási pontoknak a paramétertérben elfoglalt helye jó egyezést mutat a kiterjesztett elméleten alapuló, a nemlineáris végeselem-módszert a Newton-Raphson-módszerrel ötvöző algoritmus eredményeivel.
