Test Method for Plane Stress Fracture Toughness of Thin Sheet Metal

Wen Zheng, Kai-Ye Xiao, Hai Xu, and Zhi-Wei Guo
Abstract—In this paper, the plane stress fracture toughness (KC) of sheet metal similar to 60Si2Mn with a thickness of about 0.9mm is measured through the central crack tensile specimen (MT specimen) and the compact tensile specimen (CT specimen). The compliance calibration curve and KR curve are obtained on the basis of the reasonably designed fixture and anti-buckling device. Then the KC values are calculated by CT specimens. This paper also discussed the minimum plate width when MT specimens satisfied the requirements for validity judgement.

Index Terms—Plane stress fracture toughness, MT specimen, CT specimen, compliance calibration curve, KR curve.
