GB/T 46428.1-2025 Metallic materials—Miniature specimens of plate and rod—Part 1:Fatigue test method
Abstract
This document describes the fatigue test method for plate-shaped and rod-shaped micro-specimens of metal materials, and stipulates the principles of the test method, the specimens, the test apparatus, the test procedures, data processing, and the content of the test report.
This document is applicable to the constant amplitude low-cycle fatigue test of funnel-shaped plate specimens of homogeneous, isotropic metal materials with a stress-strain relationship exhibiting a power law, with a thickness of 0.6 mm to 2 mm. The low-cycle fatigue test of rod-shaped specimens is referred to GB/T 26077.
