Rapid Heating and Loading of 5052-H34Aluminum Alloy Sheet,

摘要

The purpose of the report is to make available to the design engineer tensile property data on 5052-H34aluminum under conditions of rapid heating and loading. The tensile property data reported are: ultimate tensile stress,ultimate yield stress (at 0.2percent offset),elastic modulus,percent total elongation,and percent uniform elongation. The uniform elongation was determined only at 0.0045in./in./sec on the transverse specimens. These tensile properties were determined at strain rates of 0.0045, 0.0262,and 0.0419in./in./sec and at temperatures from room temperature (78F) to 700F at 100-degree intervals,excluding 100and 200F. The time required to reach the test temperature was,in most cases,less than 10seconds. In addition to the tensile property data,the angle of fracture of the material was also determined. Primary consideration is given to ultimate tensile and yield properties. (Author)
