ADVANCEMENTS IN THE AUTOMOTIVE DURABILITY PROCESS
Structural integrity in terms of automotive durability is not just a calculation or a code, but a detailed process that incorporates many technical areas. The current durability process for automotive applications involves understanding operational load inputs, the stresses and strains caused and the response of the material, performing fatigue tests, calculating fatigue life and interpreting results. There are many variations on this process depending on the application, materials, available information, methods, etc. This paper presents a general approach for the durability process in automotive applications and highlights a number of new advancements. These advancements include understanding the service operating load conditions through improved usage based monitoring, characterizing new materials together with their associated damage models, enhancing and automating data manipulation through straightforward, consistent and rapid process based analysis, creating test profiles for random loading and accelerating CAE based durability analysis. The impact and importance of the advancements is illustrated by reference to each part of the durability process as well as the process itself.
