Abstract:

An elastic stress analysis was performed on a wedge specimen prismatic bar with double-edge wedge cross-section subjected to thermal cycles in fluidized beds. Five alloys IN 100, Mar-M 200, Mar-M 302, NASA TAZ-8A, and Rene 80 subjected to the same thermal cycling condition were analyzed. This condition was alternate 3 minute immersions in fluidized beds maintained at 316 degrees and 1088 degrees C 600 degrees and 1990 degrees F. The analyses were performed as a joint effort of two laboratories using different models and computer programs NASTRAN and IS03DQ. Stress, strain, and temperature results are presented. Author
