Abstract: When a structure is subjected to any sort of damage such as loadings cracks will be developed. When those structure continuously subjected to repeated loading it leads to catastrophic failure of the structure.in this study ,it is investigated that the effect of the temperature on stress intensity factor. Finite element analysis (Ansys 12.0) is used to investigate the temperature effect on stress intensity factor. A plate with both ends fixed at the top and bottom with an edge crack is tested for a temperature gradient zero at mid thickness to T0C at the edges.The temperature tested in this study are 200C, 250C, 300C, 350C, 400C, 450C and 500C.The stress intensity factor for each rise of temperature are noted. Finally it is found the the stress intensity factor is sensitive to the temperature and it is linear with increase in temperature.
