- Summary
-
This report describes investigations performed to determine experimentally the validity of the time-independent aspects of a time-dependent elasto-plastic stress and strain analysis method (published in ASD TR 61-667 Vol. 1 "Elasto-plastic analysis of structure under load and two-dimensional temperature distributions") for structures exposed to complex load and two-dimensional elevated temperature environments. An experiment specifically designed to evaluate the accuracy of the theoretical method is presented. This consisted of a test of a long flat plate subjected to step functions of load randomly combined with several two-dimensional temperature distributions. Magnitude and duration of the test variables were such that plasticity, creep and appreciable thermal stress systems were introduced. Comparisons are made of experimental total strains with analytical total strains calculated for conditions identical with the test. The degree of correlation achieved indicates verification of the analysis method within the range of test parameters selected.
