“…Additionally, a tremendous amount of work performed to date had also been devoted to correlate the rupture time between SPCT and uniaxial creep test using different methods, such as membrane stress method (Chakrabarty, 1970), equivalent creep strain method (Hyde et al ., 2010), and spherical and cone model (Yang et al ., 2017b) based on the semi-empirical approach to perform data interpretation. Among these approaches, such as Larson–Miller (LM), Orr–Sherby–Dorn (OSD) and Monkman–Grant (MG) relationships (Lorenzo et al ., 2014; Dobeš and Milička, 2002), LM model has the most extensive applications due to its simplicity by assuming the activation energy is dependent on the applied stress (Webster and Ainsworth, 2013). Similarly, in the work done by Dobeš and Milička (2008), a modified ratio of applied force to stress was proposed to correlate SPCT data with uniaxial creep test, and they found that the force measured from the SPCT is proportional to the stress in uniaxial creep test.…”

PurposeThis paper presents a review concerning the analytical and inverse methods of small punch creep test (SPCT) in order to evaluate the mechanical property of component material at elevated temperature.Design/methodology/approachIn this work, the effects of temperature, specimen size and shape on material properties are mainly discussed using the finite element (FE) method. The analytical approaches including membrane stretching, empirical or semi-empirical solutions that are currently used for data interpretation have been presented.FindingsThe state-of-the-art research progress on the inverse method, such as non-linear optimization program and neutral network, is critically reviewed. The capabilities of the inverse technique, the uniqueness of the solution and future development are discussed.Originality/valueThe state-of-the-art research progress on the inverse method such as non-linear optimization program and neutral network is critically reviewed. The capabilities of the inverse technique, the uniqueness of the solution and future development are discussed.
