Fractal Modeling and Simulation of the Developing Process of Stress Cracks in Corn Kernel

Abstract

Stress-cracks are fine fissures in grain kernel endosperm and caused by rapid drying at high temperatures. Fractal analysis on stress cracks in corn kernel was carried out in this study. The irregular and rough profile of stress cracks of corn kernel can be regarded as having the property of self-similarity statistically, and was studied according to the fractal theory. Four types of fractal propagating models of stress cracks were established. The fractal dimensions were developed. The propagating process of whole and partial sections was simulated.
