Abstract

Problems requiring experimental determination of stresses in structures subjected to high temperature environments can be categorized as problems in which it is necessary to determine:

1. Vibratory stresses only (static stresses on which vibratory stresses are superimposed are ignored).

2. Stresses caused by external loads applied over relatively long time intervals in high, but constant, positive temperature environments.

3. Stresses in structures which may or may not be subjected to external loads but which occur in environments characterized by temperature distributions varying in space and with time.
