Abstract

According to the significance of postharvest processes in increasing the life of agricultural produce and preserving their nutrition, industrial, and economic values, as well as identifying damage factors in order to reduce products' damages and losses, it is essential to acknowledge and evaluate the mechanical behavior of agricultural produce for designing and optimizing machineries. This behavior includes such determined and defined parameters as modulus of elasticity (E), shear modulus (G), and bulk modulus (K), Poisson's ratio, and viscosity, as well as imposed forces and factors effective in damages. Accordingly, rheological models (spring and dashpot), finite element, discrete elements, regression, and mass estimation using image processing are among the methods being used for this purpose. In doing so, reviewing the literature background on fruits' mechanical behavior modeling, their modeling methods were highlighted and the characteristics, capabilities, and necessary requireme

Conclusion

The literature review showed that the mechanical behavior modeling of fruits is one the major topics of the post-harvest engineering. Since the post-harvest engineering encompasses the transportation of products from farms and orchards to the product processing stage, studying the mechanical behavior of fruits has led to important progresses in developing transportation, packaging, grading, and quality measurement machineries. The reports other references show that the objective of modeling the mechanical behavior of fruits is to understand their physical and mechanical properties at the shortest time possible and with high accuracy, as well as the ability to study the different depths and layers of fruits without the limitations imposed by laboratory instruments and tools and as a nondestructive test with less cost and higher accuracy. The results of the modeling from the reviewed papers are as follows: Reviewing rheological models for mechanical behavior modeling of fruits using str
