Vehicle breakdown statistics show a clear trend: quality will be a major target for the future. This, taken together with the growing market demand for greater reliability, shows that the automobile industry needs to take action. A way to achieve this is being sought, in some cases too frantically. All the concepts which have been formulated, as yet, have a common aim: Price or cost reduction A more flexible response to market trends To boost the consumer's quality consciousness. The right response to these challenges leads directly to a reduction in development time. The first answer is a standardization of test procedures according to operating strength. The first idea and outlook was done in the SAE-Paper 790464 in 1979: “The ASSET-Technique”. Now in 1996 it has become a standard in the German car industry. [1]

The “Asset” technique sets out portray in principle how service loads can be simulated, with an adequate confidence level, test stand methods. The mathematical justification for this simulation is treated in broad outline.

During the development of safety-related components for the automobile industry we are subjected to strict guidelines and time restrictions which should not be underestimated. This is why we are forced to develop technologies to facilitate delivery of to supply safe components in very short time. The use of operating strength during the last 15 years has enabled us to reduce the number of prototypes and to inform technical designers on the essential characteristics of operationally reliable designs. With the aid of the Finite Element Method and the operating strength we will determine the following: to give the designer needed information as to whether the design is able to meet the requested service life values, or What has to be done to achieve theoretical and experimental guidelines using these methods, to facilitate service life estimation prior to the prototype stage.
