In this paper, numeral and experimental analysis of composite metal vessel is investigated under variable pressure loading. For this purpose, a sample of multi section cylindrical vessel is considered. The pizo electric 1000 bars sensors are used to measure pressure. The sensors are installed in the holes on the metal cylindrical vessel. The amplification parts are used to adjust sensors. The test is done under dynamic loading. The results are recorded by data logers in pressure-time chart. The aim of this study is to optimize the weight and strength of the vessel with using trial and error by numeral analysis inverse explosive loading. In order to, a sample of multi section cylindrical vessel is analyzed with abaqus finite element software. The load in the vessel is derived by charts from experimental tests. The load obtained from experimental tests as a dynamic load is analyzed and compared with metal vessel and metal- Composite vessel. The results obtained from abaqus finite element software have discussion in different case. Finally, geometric and material properties of liner and composite is suggested for optimize the weight and strength of the vessel.

Keywords: Variable pressure, Metal-composite vessel, Finite element analysis, Dynamic Load, Experimental test
