Isogeometric pre-buckling analysis of laminated shallow shells

Abstract The deployment of laminated shallow shells has achieved significant traction across the domains aerospace, mechanical, and marine engineering, where ensuring structural stability remains a major consideration. In this paper, pre-buckling analysis is proposed based on isogeometric model. geometric structure displacement shell are represented by NURBS basis functions with fewer control points, nonlinear behavior shown path-following method. result shows that critical points associated material, which provides certain reference for further optimization parameters to improve performance shells.
