Abstract
Hydrodynamic theory of hypervelocity penetration is widely used to describe the penetration of long rods because of its simplicity and computational efficiency. In this paper, the penetration resistance is evaluated from the crater size generated by hypervelocity impact and is combined with one-dimensional analytical model to predict DOP (depth of penetration). Then, a computational formulation for change of energy per unit DOP is derived and the influences of different parameters on DOP are analysed. At last, in the multi-layer target, the effect of the layer arrangement is considered from the energetic point of view. The method for determining the effective arrangement of material layers with maximum energy variation is proposed. The validity of our approach is confirmed by comparing our analytical results with the AUTODYN results and literature.
期刊介绍：
Mechanics Research Communications publishes, as rapidly as possible, peer-reviewed manuscripts of high standards but restricted length. It aims to provide:
• a fast means of communication
• an exchange of ideas among workers in mechanics
• an effective method of bringing new results quickly to the public
• an informal vehicle for the discussion
• of ideas that may still be in the formative stages
The field of Mechanics will be understood to encompass the behavior of continua, fluids, solids, particles and their mixtures. Submissions must contain a strong, novel contribution to the field of mechanics, and ideally should be focused on current issues in the field involving theoretical, experimental and/or applied research, preferably within the broad expertise encompassed by the Board of Associate Editors. Deviations from these areas should be discussed in advance with the Editor-in-Chief.
