Abstract
The existing systems in operation, for instance in mechanical, civil, transport, electrical engineering, etc., are usually considered as having only spatial r and fast time t-dynamic coordinates and properties. This description is sufficient if only the design properties are considered, optimized, and the dynamic behaviour is simulated. But when the mechanical properties of real systems in operation are considered, which means taking into account imperfections and damage that have appeared during the manufacturing stage, and when their evolution in operation is considered, one should introduce the concept of life with the lifetime θ, where the damage evolution can proceed and can be measured. The life properties depend on the environmental conditions as well as on the operational ones. Both can introduce faults and damage into the system, which, if they exist, will have an instantaneous effect or will affect the mechanical system under operation in an evolutionary manner to a certain extent. In consequence, a holistic approach is needed in order to model the total dynamics of the system in operation.
