摘要：

The nonlinear deformation of flexible composite shells with reinforced curved holes under static loading is studied. Problems of this class are formulated, and a numerical method for solving them with allowance for finite deflections is outlined. The distributions of stresses, strains, and displacements along the boundary of the hole and in the zone of stress concentration in an orthotropic cylindrical shell with a reinforced hole subjected to uniform internal pressure are examined. The results are analyzed and compared to the solutions of the corresponding linear elastic problems for a shell with a nonreinforced hole. © 2014, Springer Science+Business Media New York.
