“…The mechanical simulation of fruits with a multiscale geometrical model linking the macroscopic (whole fruit) scale through the mesoscopic (tissue) scale to the microscopic (cellular) scale (Fratzl ; Aizenberg and others ) would be scientifically and commercially valuable in understanding how external mechanical damage to fruit causes internal cellular damage and other changes that lead to bruising. There are some kinds of fruits such as apple (Dintwa and others ), watermelon (Sadrnia and others ), and tomato (Li and others , ) for which multitissue geometrical models have been developed to simulate the complex impact and compression mechanical behavior. More realistic fruit models would be more accurate in simulations using finite element analysis, but they would take a long time to compute, maybe even unachievable within the limits of existing computing power (Li and others ).…”

Well-designed and well-operated postharvest mechanical handling processes are vital if fresh fruits are to enter markets with minimal damage. The susceptibility of fruit to quality loss during handling is largely determined by mechanical contact and damage. This article reviews current understanding concerning the effect of impact and other mechanical contacts on fruits. It also discusses the major mechanical models that represent the interaction between fruits or a fruit and a surface. In total, 25 mechanical models associated with compression and impact behaviors of fresh fruits, mainly characterizing such behavior between 2 deformable spherical bodies and between a deformable spherical body and a rigid plate are reviewed. Finally, possible future research directions are discussed. The main challenge in fruit handling is to recognize and prevent microscopic damage to fruits, especially internal tissue/cell damage and microcracks resulting from multiple/repetitive impacts and compressions.

“…Dintwa et al [42] studied apple bruise area, which appears during the contact against a fixed plate as well as another apple. They applied the MSC.Marc®/Mentat® system for model determining which enabled to calculate the geometrical nonlinearity (large deformations) and material properties (plasticity) including contact stresses and open or closed slots, based on the finite element method.…”

Biological material is exposed to different type loads during the harvesting, sorting, and transport. The contact with the hard element of the box or the harvester causes damage to the internal structure. Long-term static loads and hitting by another carrot root are the most common type of mechanical damage occurring in the post-harvest process. Because of the characteristic shape of agricultural products, compression force focused on a small area. The main purpose of this study was to determine the discrete model of carrot root as well as to verify it based on the displacement distribution.For determining an experimental model, the collected data were statistically processed. To verify the obtained model, the COSMOS/M software was applied. As a result of this study, a calculation model was presented, which allowed the assessment of surface pressures on the carrot root area, which occurred during the contact with different shaped elements in selected phases of technology process.

“…Dintwa et al [14] studied the possibility of modeling errors when simulating postharvest packaging in bulk using a discrete element method and constructed a finite element model to analyze the dynamic process of collision between individual apples and that between the apples and the wall. Zhang et al [15] conducted research into the design and mechanical properties of a PVC elastic thinwalled packing box for eggs.…”

It is important to study the properties and mechanics of egg drop impacts in order to reduce egg loss during processing and logistics and to provide a basis for the protective packaging of egg products. In this paper, we present the results of our study of the effects of the structural parameters on the mechanical properties of an egg using a finite element model of the egg. Based on Fluid-Solid coupling theory, a finite element model of an egg was constructed using ADINA, a finite element calculation and analysis software package. To simplify the model, the internal fluid of the egg was considered to be a homogeneous substance. The egg drop impact was simulated by the coupling solution, and the feasibility of the model was verified by comparison with the experimental results of a drop test. In summary, the modeling scheme was shown to be feasible and the simulation results provide a theoretical basis for the optimum design of egg packaging and egg processing equipment.
