【 摘 要 】

The paper describes a work focused on the process of perforation of aluminum alloy sheet at a wide range of specimen temperatures. This has been obtained by using the specially designed thermal chamber to heat specimens before impact. Based on this experimental series. Experimental, analytical and numerical investigations have been carried out analyze the perforation process, the ballistic properties of the aluminum alloy impacted by a conical nose shape projectile are studied. The experimental investigations have been extended by numerical simulations using a general purpose software Abaqus/Explicit. A good correlation has been obtained. To study the temperature effects. The range of available temperatures is from the room ambient temperature up to 300 °C. The time needed to heat the specimen and to stabilize its temperature is 20 minutes. This study has allowed to discuss the ballistic behavior and resistance of sheet plates of the aluminum alloy under dynamic loading and different temperatures.
