Investigation of the dynamic behavior of three-layer cylindrical shells of elliptical form under internal axisymmetric pulse loading

The results of the assessment dynamic behavior three-layer cylindrical shells circular and elliptical cross-sections under internal impulse loading are given. finite-element method was used to calculate indicators stress-strain state (SSS) such structures by NASTRAN software complex. values normal deflections stresses three forms intersection determined. A comparative analysis these with uneven performed.
 shape curvature cross section thin-walled composite significantly affect their SSS loading.
 Replacing a structure an one increasing ratio semiaxes leads increase in middle surface structure.
