Three Dimensional Finite-Element Elastic Analysis of a Thermally Cycled Double-Edge Wedge Geometry Specimen.

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)
