When a projectile penetrates a target at high speed, the charge loaded inside the projectile usually bears a high overload, which will consequently severely affect its performance. In order to reduce the overload of the charge during the penetration process, the structure of the projectile was improved by adding two buffers at both ends of the charge. In this study, the mathematical expressions were first gained about the axial buffering force generated by the thin-walled metal tube, aluminum foam, and the composite structure of aluminum foam-filled thin-walled metal tube when they were impacted by the high-speed mass block through reasonable assumptions and stress analysis. During the experiment on the high-speed projectile penetrating reinforced concrete target, the acceleration curve of the charge and the projectile body were obtained. The results show that the maximum overload that the charge was subjected to during the launch and penetration process was significantly reduced, and the change in overload, which the charge was subjected to during the penetration process, was also less obvious.

Thin Walled

In the present era of supersonic and hypersonic flight, structural analysts are well aware of the new problems that arise from the exposure of aircraft and missile structures to elevated temperatures. The task of solving these problems is in its early stage of development. Since the problems are diversified in nature, a different method of solution has to be developed in each case. It is probable that in some cases radically new techniques may have to be devised. Until such time, the structural designer is forced to take a realistic view and use satisfactory extensions of existing methods of analysis.

To save material, the safety factor of pressure vessel design standards is gradually decreased from 5.0 to 2.4 in ASME Boiler and Pressure Vessel Codes. So the design methods of pressure vessel should be more rationalized. Considering effects of material strain hardening and non-linear structural deformation, the elastic-plastic stress analysis is the most suitable for pressure vessels design at present. This paper is based on elastic-plastic theory and considers material strain hardening and structural deformation effects. Elastic-plastic stress analyses of pressure vessels are summarized. Firstly, expressions of load and structural deformation relationship were introduced for thin-walled cylindrical and spherical vessels under internal pressure. Secondly, the plastic instability for thin-walled cylindrical and spherical vessels under internal pressure were analysed. Thirdly, to prevent pressure vessels from local failure, the ductile fracture strain of materials was discussed.

This article focuses on the analysis of stresses within a thin-walled vessel. Focused on rotary symmetrical shell, boundary faults arising at the junction of the cylindrical part of the vessel and its bottom are monitored. The bottom of the vessel is designed in three variants and obtained values of stresses are compared. From the obtained results it is possible to assess which form of the bottom is preferred.
