[ 1 ] - بررسی آسیب در تیرهای بتن مسلح زیر بارگذاری انفجاری (آزمایش میدانی و شبیه‌سازی عددی)

One way of thermal stability methods and ablation improving for polyurethane elastomers to solid propellant rocket insulation, is using of fillers with high ablation property such as silica particles. In this research, first polyurethane-silica composites (16, 25 and 38% by weight) and polyurethane-silica nanocomposites (5, 10, 16 and 25% by weight) were prepared and then interaction, morpholog...

[ 2 ] - کاربرد لایه‌های جاذب انرژی برای کاهش اثر بار انفجار بر دال‌های بتن مسلح

Reduction of structural damages due to the blast attacks is the main priorities of civil defense. Since most researchs in this field are concentrated on stability and strength increasing of the structures, this paper provides an effective method to blast load mitigation on the structures. In this study, twelve full-scale samples in four groups have tested under the same weight and stand-off of ...
