Use of different methods of local SPD (surface plastic deformation) to reduce stress concentrator impact upon profile surfaces of transport machinery parts
Abstract and keywords
Abstract (English):
It is defined that in the course of machining complex profile parts operating under heavy alternating loads, in critical transition areas of profile conjugated surfaces there are formed local technological stress concentrators promoting the formation and growth of fatigue cracks and further destruction of operating parts. There are developed and introduced methods to reduce the values of such stress concentrators on the basis of the application of different methods of local surface plastic deformation.

Keywords:
technological stress concentrators, profile surface, local transition areas, fatigue cracks, fatigue resistance, thread, gears, turbine blades
