This paper presents the study on influence external pressures on vibration of functionally graded materials thin-walled cylindrical shell supported. The functionally graded materials (FGMs) properties are graded in the thickness direction of the shell. FGMs are advanced composite materials, consisting of different types of materials, in which the properties shift continuously from one material ...

Thin-walled structures have been used in many fields due to their superior mechanical properties. In this paper, two types of hierarchical multi-cell tubes, inspired by the self-similarity Pinus sylvestris, are proposed enhance structural energy absorption performance. The finite element models established validate crashworthiness performance under axial dynamic load. theoretical model mean cru...

Thin-walled structures are of great interest because their use as lightweight components in aeronautical and aerospace engineering. The fabrication these by additive manufacturing (AM) often produces undesired warpage the thermal stresses induced process components’ reduced structural stiffness. objective this study is to analyze distortion several thin-walled fabricated Laser Powder Bed Fusion...
