تحلیل تجربی سرعت حد بالستیک اهداف بتنی هوادار سبک اتوکلاو شده تحت نفوذ پرتابه صلب
Authors
Abstract:
In this paper experimental analysis of ballistic limit velocity of autoclaved aerated concrete (AAC) targets under rigid projectile penetration is presented. Industrial blocks with dimension of 600*250*200(mm) were cut into 125*125*50(mm) samples, impacted by gas gun using three different nose shaped projectiles (flat, ogive and conic). In this study damage mechanism and penetration depth were investigated and compared with conventional concrete which revealed significant difference in the initial penetration and cratering phase. It is predicted that ballistic velocity limit for conical projectile is lower than ogive ones and flat noses have the highest. The result compared and the difference between penetration mechanisms and cratering were discussed and investigated.

تحلیل نفوذ پرتابه های صلب در اهداف بتنی بر مبنای تئوری انتشار موج شوک (علمی- ترویجی)
Due to the importance of concrete structures, the field of projectile penetration into concrete targets has attracted increasing research efforts. Gao et al. presented a new method for penetration analysis into concrete targets. Propagation of shock waves due to impact is the base of this method. The aim of the present study is to investigate and modify this model. In this research, first a bri...

In this paper, the penetration process of the follow warhead in anti structure tandem projectiles is investigated by numerical and experimental methods. These projectiles are usually shaped charge or EFP. In the follow projectile, geometry and material are considered as the two main parameters. Numerical modeling of the problem has been performed in AUTODYN code. The numerical results have ...

در این مقاله، فرآیند نفوذ پرتابههای پیشرو در سرجنگیهای دو مرحلهای ضد استحکامات به روشهای تجربی و عددی مورد بررسی و تحلیل قرار گرفته است. معمولاً این نوع پرتابهها از نوع خرج گود و یا شکل یافته انفجاری میباشند. در این تحقیق هندسه و جنس لاینر پرتابههای پیشرو به عنوان دو پارامتر اساسی در فرآیند نفوذ مورد توجه ویژه قرار گرفته است. آزمونهای برخورد اجرا شده بر روی اهداف بتنی توسط پرتابههای پیش...
