Study of High-Temperature Mechanical Properties of Q235 Galvanized Sheet

摘要

On summary of the existing research work on high temperature mechanical property and stress-strain relations of the commonly used metallic materials in engineering, study of the mechanical property of Q235 thin-walled galvanized sheet with depth of 2mm in elevated temperature was presented. A series of steady tensile tests and transient tensile tests of the material was put forward for different temperatures using high temperature furnace, and the mechanical property indexes such as elastic modulus, yielding strength, ultimate strength and elongation of the material for different temperature were obtained. The results obtained here can be used for fire-resistance computation and design of the structure constructed with the material.
