Abstract Scope |
Thin fine grain layers are often generated in the vicinity of frictional interfaces in manufacturing processes as a result of severe shear deformation. These layers change surface properties of machine parts. The latter affects the performance of structures and machine parts under service conditions. The strain rate intensity factor is the coefficient of the leading singular term in a series expansion of the equivalent strain rate in the vicinity of maximum friction surfaces. The objective of the present paper is to develop a general approach to use the strain rate intensity factor for predicting the evolution of fine grain layers. The paper includes a conceptual approach, experimental results on upsetting and drawing, and a special numerical method for calculating the strain rate intensity factor. The latter is necessary since the strain rate intensity factor appears in singular solutions, and conventional finite element methods are not capable of calculating this factor. |
