Abstract: Abstract In this paper, the buckling performance of curvilinearly grid-stiffened variable-stiffness composite cylindrically curved panels subjected to in-plane compressive loads under different boundary conditions is addressed. A Python-Abaqus script is developed to perform the buckling… read more here.

DOI: 10.1177/09544062211029329
Abstract: This paper presents the buckling behavior of the grid stiffened composite conical shell subjected to the lateral pressure. A smeared method is employed to equivalent grid structure into a layer. For this purpose, a typical… read more here.
