Dynamic instability zone analysis of laminated piezoelectric cylindrical shell with delamination under hygrothermal effects

Stability of Composite Cylindrical Shells with Nonclassical Hygrothermal–Electro–Elastic Coupled Loads

“…Ebrahimi and Mahesh (2020) examined hygrothermal postbuckling of multiscale doubly curved piezoelectric shells. Tang and Dai (2021) performed dynamic instability zone analysis of laminated piezoelectric cylindrical shells with delamination under hygrothermal effects. Lal et al (2012) analyzed second order statistics of the post-buckling response for piezoelectric laminated composite cylindrical shell panels subjected to hygrothermal-electro-mechanical loads with random system properties.…”

“…From the literature review above, it is clear there exist two major limitations: (i) the buckling analysis of HTEE cylindrical shells was rarely reported in the open literature (Ebrahimi and Mahesh 2020;Hajmohammad, Zarei, Farrokhian and Kolahchi 2018;Lal, Saidane and Singh 2012;Tang and Dai 2021), consequently the influence of multi-field coupling effects on stability behaviors of such shells have not been revealed (Vinyas and Kattimani 2017); (ii) the end conditions of HTEE cylindrical shells were assumed to be free at the pre-buckling stage, and therefore it results in overestimated critical buckling loads (Almroth 1966;Teng and Rotter 2014;. Motivated by the two key issues, an accurate nonlinear buckling analysis of HTEE cylindrical shells is performed by considering pre-buckling effects (Sun et al 2016).…”
