Influence of damage assessment on mechanical stress and deformation responses of porous graded curved (single/doubly) panel structure

The present study develops a numerical solution technique to assess the impact of damage, curvature, and porosity on the functionally graded material (FGMs) structure. Initially, the structural model is derived mathematically using higher‐order kinematics in this framework of a corresponding single‐layer theory. The structural model is derived mathematically, and the deflection and stress values are obtained computationally using in‐house MATLAB code. Primarily, the concurrence behavior of the developed model is checked, and further, the accuracy of the present model is verified by contrasting the outcomes with the data existing in the open domain. The maximum deviation observed between the reference and present results in stress and deflection responses is 7.1% and 2.68%, respectively. The validated model is further utilized to understand the effects of different geometrical porosity distributions, damages, and shapes.
