Bu metod Amerkan Allis-Chalmers firmas\u0131n\u0131n teset laborant\u0131 Fred C. Bond taraf\u0131ndan geli\u015ftirilmi\u015ftir ve g\u00fcn\u00fcm\u00fczde de ta\u015flar\u0131n k\u0131r\u0131lma direncini belirlemede yayg\u0131n olarak kullan\u0131lmaktad\u0131r.<\/p>\n

Bir ta\u015f\u0131n k\u0131r\u0131labilirli\u011fi veya k\u0131r\u0131lmaya kar\u015f\u0131 olan direnci, ta\u015f\u0131 k\u0131rabilmek i\u00e7in harcanmas\u0131 gereken enerjinin \u00f6l\u00e7\u00fclmesi ile bulunur. Bu \u00f6zellik, k\u0131r\u0131c\u0131 tip ve ebatlar\u0131n\u0131n do\u011fru se\u00e7ilebilmesi i\u00e7in son derece \u00f6nemlidir.<\/p>\n

Bu test i\u00e7in 70x70mm kare bir delikten ge\u00e7ebilecek, ancak 55x55mm bir delikten ge\u00e7meyecek b\u00fcy\u00fckl\u00fckte 30 adet, olabildi\u011fince k\u00fcbik \u015fekilli ta\u015f numunesi gereklidir. Bu numuneler, ayr\u0131 ayr\u0131 test d\u00fczene\u011fine yerle\u015ftirilerek test edilir. Test d\u00fczene\u011fi 2 adet \u00e7eki\u00e7ten olu\u015fur. Bu \u00e7eki\u00e7ler ta\u015f numunesine iki taraf\u0131ndan ayn\u0131 anda \u00e7arparak k\u0131rmaya \u00e7al\u0131\u015f\u0131r. \u00c7eki\u00e7ler belli bir y\u00fckseklikten serbest b\u0131rak\u0131l\u0131r ve sarka\u00e7 hareketi ile d\u00f6nerek ta\u015f numunesine \u00e7arpar. Ta\u015f numunesi k\u0131r\u0131lana kadar \u00e7eki\u00e7ler giderek daha yukar\u0131dan b\u0131rak\u0131l\u0131r. Ta\u015f numunesini k\u0131rmak i\u00e7in gerekli olan enerji ta\u015f\u0131n darbe dayan\u0131m\u0131 olarak isimlendirilir ve a\u015fa\u011f\u0131daki form\u00fclle bulunur.<\/p>\n
