摘要
The spring-back phenomenon in rolled copper and aluminum sheets has been studied in experiment. The time dependences of strain at bending of specimens under permanent load have been described by power functions with a fractional index. The anisotropy of the spring-back phenomenon has been revealed. A mathematical model is proposed which describes the spring-back basing on fractal concepts of the relaxation processes under external permanent stress.
