Dynamic Compressive Deformation Characteristics of Free-Cutting Brass And Yellow Brass at High Strain Rates
고변형률 압축 하중에서 쾌삭 황동과 황동의 동적 변형 거동 특성

Abstract
Mechanical properties of the materials used for transportations and industrial machinery under high strain rate loading conditions such as high impact loading are required to provide appropriate safety assessment to varying dynamically loaded mechanical structures. The Split Hopkinson Pressure Bar(SHPB) technique with a special experimental apparatus can be used to obtain the material behavior under high strain rate loading conditions. In this paper, the dynamic deformation behavior of a brass under both high strain rate compressive loading conditions has been determined using the SHPB technique.
