Providing of complex systems durability. Structural aspects

This paper is devoted to the researching of durability of compound technical. All systems are influenced by outside factors. It is important to know how long the system will be able to functionate with given damages. The propagation of impacts through the system simulation is suggested. This simulation let to find most strong and weak points in its structure. It shows clearly the dependence of the system element durability from the element place in the structure.
