Thermoelastic investigation of damage evolution in small stainless steel pipework
At 13th International Conference on Experimental Mechanics (ICEM07).
01 - 06 Jul 2007.
This paper describes work on damage studies in small cold worked pipe sections. The effect of material heat treatment on the sensitivity of the thermoelastic constant to exposure to plastic strain is assessed. It is shown that strain hardening plays an important role in modifying the thermoelastic constant. X-ray computed tomography has been use to assess the geometry of the deformed cross-section of pipe and to identify the presence of damage. Finally the potential of thermoelastic stress analysis for damage assessment in the pipe work is established.
