摘要
Statical problems for thin orthotropic toroidal shells with superelliptical or supercircular cross-sections are considered using a procedure based on the variational-difference method, the method of Lagrangian multipliers, and mixed functionals. Because of membrane locking, this problem can joint the ranks of the so-called pathological tests.
