ASTM E238 Pin-Type Bearing Testing of Metallic Materials

ASTM E238 | Metals | Bearing Strength

ASTM E238 describes the determination of the bearing strength and the bearing yield strength of metallic materials by a pin-type bearing test. The bearing load is generally applied to the specimen through a close-fitting cylindrical pin that is harder and stronger than the test specimen.

Bearing strength is defined as the maximum bearing stress which a material is capable of sustaining. Bearing yield strength is the bearing stress at which a material exhibits a specified limiting deviation from the proportionality of bearing stress to bearing strain. Bearing properties are useful in the comparison of materials and design of structures under conditions where the pin is not restricted.

Before conducting ASTM E238, it is important to read the entire specification in the relevant ASTM publication.
