Dart zarbasi sinovi erkin tushayotgan yarim shar shaklidagi dartdan foydalanadi, u vertikal ravishda qisilib ushlangan film namunasiga tushadi. Film zarba natijasida buziladi yoki unga chidaydi. Dart og'irligini bosqichma-bosqich oshirish va buzilishlar sonini hisoblash orqali operatorlar ma'lum bir buzilishni keltirib chiqaradigan og'irlikni aniqlaydilar. 50% nosozlik darajasi<\/strong>, bu materialning zarbaga chidamliligini ifodalaydi.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
