Crack Arrest Temperature Formula of Low Alloy Steel Plate Based on Temperature-gradient Double Tension Test

More Information
  • Received Date: December 24, 2015
  • Based on the analysis of crack arrest behavior with principle of conservation of energy,the relationship between crack arrest temperature measured by temperature-gradient double tension test and stress,plate thickness and impact toughness measured with sample surface at -40 ℃ was studied with 52 groups of test data of low alloy steel plates. The crack arrest temperature formula was founded as Tk=-66.1+0.011 8·(σ·t2/KV2)。.
