Характеристики сопротивления ударному изгибу пластичных сталей, применяемых в краностроении

Abstract

Using plastic steel 09Г2С it was shown by means of experiment that an impact elasticity depends on specimen form and dimensions and consequently can not be used as material characteristic. The alternative characteristic was offered – specific impact elasticity, which takes into account specimen plastic deformation parameters. It was shown that for plastic steels specimen destruction energy can be not proportional to failure surface area.
