The model employs the Gurson - Tvergaard yield function together with the Norton - Baily power creep law. Rupture occurs at the end of a tertiary creep stage when the load - carrying capacity of the test - piece vanishes. Formulations for both uniaxial and triaxial conditions are given. Comparisons among the predictions of the present model and experiments for a vast number of data points indicate satisfactory agreement. A relation incorporating steady - state creep rate, rupture strain and rupture time is suggested. Furthermore acceptable correlation of the creep - rupture strength and creep strength to cause a specified creep strain is obtained. Opini Anda Klik untuk menuliskan opini Anda tentang koleksi ini!
