Approaches and methods for an estimation of physical wear (life expense) for technical objects are analyzed. Calculation examples by various techniques are resulted. A variety of treatments for physical wear (life expense) of technical objects is shown. The concept of the life expense for the car as a weight-average value for the life expenses of its basic parts is entered. The nonlinear model of life expense determination for the basic part of the car depending on its run and age is presented.
