An approach developed to solve static problems for longitudinally corrugated elliptic cylindrical shells is used to analyze the influence of their geometric parameters and thickness on the stress-strain state. The circumferential distribution of stresses and displacements is analyzed for different values of the aspect ratio and number of corrugations Keywords: corrugated elliptic cylindrical shell, stress state, number of corrugations, aspect ratio Introduction. Noncircular cylindrical shells with arbitrary boundary conditions subjected to nonuniform or local loads are widely used in many fields of engineering [13,14]. Unlike circular cylindrical shells, there are few solutions to stress-strain problems for noncircular cylindrical shells. Spline functions and discrete orthogonalization made it possible to solve static problems for elliptic [2,8,12] and longitudinally corrugated [11] cylindrical shells. Of interest is to solve static problems for noncircular cylindrical shells with more complex cross section and to analyze their stress-strain state.Here we use the approach developed in [10] to analyze the stress-strain state of longitudinally corrugated elliptic cylindrical shells. We start with the equations of the Donnell-Mushtari-Vlasov theory of shells [1,4,7].1. The datum surface (mid-surface) of a noncircular cylindrical shell has the following first quadratic form:
