Experimental evaluation of the FDS-based equivalence approach for the mission synthesis in accelerated life tests.

This paper deals with the application of a method conceived to synthesize stationary vibration profiles with limited duration starting from long lasting reference environmental data. The aim of the research is to experimentally verify the soundness of the approach by performing simple tests on specimens purposely conceived. This paper recalls the background of the method, illustrates the experimental setup and procedures, and finally report the results of some tests that point out critical issues associated with the high sensitivity of the method application with respect to a parameter related to the material characteristics (namely the fatigue curve slope in the Wholer diagram).
