Influence of the Variations of Orthotropy Parameters on the Stress State of Hollow Cylinders with Concave Corrugated Cross Sections

In the three-dimensional statement, by the method of approximation of functions by discrete Fourier series, we analyze the influence of orthotropy parameters on the stress state of hollow cylinders with cross sections in the form of connected concave semicorrugations subjected to the action of internal pressure under certain conditions on the ends. The results of investigations of the stress state are presented in the form of plots and a table.

Analysis of the Stress State of Hollow Cylinders with Concave Corrugated Cross Sections

In the three-dimensional statement, by the method of approximation of functions by discrete Fourier series, we perform the analysis of the dependence of the stress state of a hollow cylinder whose cross section has the form of joined concave semicorrugations subjected to the action of internal pressure under certain conditions imposed on the end faces on the thicknesses and curvatures of the cross sections of the cylinders caused by the changes in the number of semicorrugations. The results of the solution of the problem are presented in the form of the plots of distributions of the fields of displacements and stresses.

Investigation of the Stress State of Noncircular Hollow Cylinders of Complex Shapes with Different Curvatures

We study the stress state of a hollow cylinder with cross section in the form of connected convex semicorrugations under certain conditions imposed on the ends and external loading of the lateral surfaces in the 3D statement. For the solution of the problem, we use the approximations of functions by discrete Fourier series. The results of calculations are presented in the form of the plots of dependences of displacements and stresses on the curvature of cross section of the cylinder.

Stress State of Hollow Cylinders With Convex Corrugated Cross Sections

The problem of equilibrium of hollow cylinders whose cross sections have the shape of connected semicorrugations is studied in the three-dimensional formulation. The cross section is specified by a continuous curve (shortened epicycloid). The problem is solved by using a numerical-analytical approach based on the application of the methods of separation of variables and approximation of functions by discrete Fourier series and the numerical method of discrete orthogonalization. The results of solution of the problem are presented in the form of the plots of the fields of stresses and displacements.

Study of stress concentration in short hollow cylinders of transversely isotropic materials

The axisymmetric stress state of hollow cylinders made of tranversely isotropic materials with a longitudinal axis of isotropy is examined in a three-dimesnional formulation. An analytical solution is obtained by using homogeneous solutions written in Kosmodamianskii's form. Results of calculations of stress concentration are given for different materials as a function of the relative thickness and relative external radius of the cylinder.
