Identification of the pulse axisymmetric load acting on a composite cylindrical shell, inhomogeneous in length, made of different materials

The problem of identifying the load acting on elements structures belongs to class inverse problems mechanics a deformable solid, which are often incorrect. Solving such is associated with instability calculation results, requires development special methods for their research. This predetermines relevance this study. object study single-pass cylindrical shell consisting two rigidly fastened butt-fastened sections made different materials. Each shells assumed be elastic isotropic, having cross-section medium thickness. equations axisymmetric deformation used within framework Timoshenko hypotheses. An approach solving direct and discretely heterogeneous objects proposed, implies conditional separation along length, followed by addition functions fictitious loads. main analytical relationships building system integral Volterra given, an analytic-numerical solution derived. final ratios have been obtained, make it possible calculate kinematic force parameters in process non-stationary deformation. arbitrary loads that length solved general form. algorithm restoration pulse has developed, robust errors initial data (about 5 %). material related can significantly advance methodology structural
