Paper Title:
Fracture Toughness and Fatigue Crack Growth Behavior of Rail Track Material
  Abstract

Fracture toughness KC and fatigue crack growth behavior of commuter train’s rail track material used in Klang Valley, Malaysia was investigated. Two different tests were performed in accordance to ASTM E399 and E647 testing procedures using single edge notch bend (SENB) and compact tension (CT) specimens, respectively. The results showed that the average KC value of the rail track material was 51.7 MPa√m. On the other hand, from the fatigue crack growth test, both longitudinal (LD) and short-transverse (TD) direction specimens demonstrated identical Paris’ Law constants C and m of 1.3 x 10-12 m/cycle and 3.54, respectively. Prediction of bending fatigue life of rail track material using the above obtained parameters showed a good agreement with the experimental results.
