FRACTURE MECHANICS ANALYSIS OF THERMAL STRAIN FATIGUE LIFE FOR THE SINTERING MACHINE PALLET

Abstract

Abstract: In recent years elastic-plastic fracture mechanics has developed rapidly and is widely used to solve various engineering problems. The application of elastic-plastic fracture mechanics on the pallet of sintering machine is approached in detail for the first time in the present study. The theoretical results were compared with the actual data determined from sintering machine pallet. Results show that good agreement was achieved between the method suggested by the author and the actual data. The basis of determining design of the sintering machine pallet in iron and steel engineering has been provided and it will result in great economic benefits.

Key words: pallet, thermal strain, fatigue life, fracture mechanics
