J积分法测定E5015焊缝断裂韧性

Test the Fracture Toughness of E5015 Weld Based on J Integral Method

以ASTM E813-89试验标准为依据,采用J积分法,用紧凑拉伸标准试件在MTS-810疲劳试验机上测量Q345钢的常用焊条E5015焊缝的断裂韧性,为工程应用提供重要的材料参数.

Based on ASTM E813-89 test standard,this paper measures the E5015 weld＇s fracture toughness with the compact tension standard specimen through the J integral method in MTS-810 fatigue test machine,and the E5015 weld is a electrode often used by Q345 steel,and the test results provide an important basis for engineering application.
