Bearing strengths of some aluminum-alloy permanent-mold castings /

Two values, one for edge distances of 1.5 times pin diameter and one for edge distances of 2 times pin diameter, are proposed for both the ratio of bearing ultimate to tensile ultimate strength and the ratio of bearing yield to tensile yield strength as a basis for selection of allowable bearing values for the design of B195-T4, B195-T6, and 356-T6 aluminun-alloy permanent-mold castings.Results are presented in this paper of bearing tests made to determine bearing ultimate and yield strengths of aluminum-alloy permanent-mold castings of B195-T4, B195-T6, and 356-T6, and to compare the ratios of bearing to tensile properties obtained with similar data from sand-castings of like materials.NACA TN No. 2312."February 1951."Two values, one for edge distances of 1.5 times pin diameter and one for edge distances of 2 times pin diameter, are proposed for both the ratio of bearing ultimate to tensile ultimate strength and the ratio of bearing yield to tensile yield strength as a basis for selection of allowable bearing values for the design of B195-T4, B195-T6, and 356-T6 aluminun-alloy permanent-mold castings.Results are presented in this paper of bearing tests made to determine bearing ultimate and yield strengths of aluminum-alloy permanent-mold castings of B195-T4, B195-T6, and 356-T6, and to compare the ratios of bearing to tensile properties obtained with similar data from sand-castings of like materials.Mode of access: Internet
