Nonlinear deformation of axisymmetrically loaded rotation shell based on FEM with different variants of definitional equations
A revolver suicideboys curvilinear finite element of the median line of an axisymmetrically loaded shell of revolution with a stiffness matrix of $8{ imes} 8$ size is used when choosing nodal unknowns in the form of displacements and their first derivatives is used.The constitutive equations at the loading step are implemented in two versions.In th
