Abstract
The transient responses of the curved shell panels are examined under thermo-mechanical loading and verified experimentally. The damaged shell model is formulated mathematically considering polynomials of higher-order based on isoparametric finite element (FE) steps. The dynamic (time-dependent deflection) responses are evaluated numerically using developed computer code in MATLAB, utilizing Newmark's constant average acceleration method. The accuracy of the present model is proven by equating the consequences with the available data in the published literature. Additionally, a few experimentations have been accomplished and outcomes are equated with the numerical solution to show the effectiveness of the present developed numerical model. Further, the impact of damages (debond and/or crack), numerous structural input parameters (curvature ratio, shell geometry) and temperature on the curved shell panel is demonstrated and presented through a wide variety of numerical examples.
