“…During the puncture simulation, the contact force decreased by 52% (ranging from 19 to 9 N) and the deformation was decreased by more than 27% (ranging from 1.45 to 2.2 mm). Overall, the results suggested that there was a clear influence of these properties for the firmer fruit resulting in a stiffer response during yielding [ 28 , 29 ]. The results were in agreement with the earlier research conducted by [ 21 ] to determine the mechanical responses in tomatoes under quasi-static compression.…”

This study aims to develop a finite element (FE) model to determine the mechanical responses of Exotica papayas during puncture loads. The FE model of the puncture-test was developed using the ANSYS 19.1 software. The proposed framework combined the finite element method and statistical procedure to validate the simulation with the experimental results. Assuming the elastic-plastic behaviour of papaya, the mechanical properties were measured through tensile test and compression test for both skin and flesh. The geometrical models include a quarter solid of papaya that was subjected to a puncture test with a 2 mm diameter flat-end stainless-steel probe inserted into the fruit tissues at 0.5 mm/s, 1 mm/s, 1.5 mm/s, 2 mm/s, and 2.5 mm/s. The FE results showed good agreement with the experimental data, indicating that the proposed approach was reliable. The FE model was best predicted the bioyield force with the highest relative error of 14.46%. In conclusion, this study contributes to the usage of FE methods for predicting the puncture responses of any perishable fruit and agricultural products.

“…Celik (2017) focused on the issue of susceptibility to bruising through determination of stresses and deformation states of pears in dynamical cases of the impact with a nonlinear stimulation of the finite elements method. Imprecision of analyses performed with the FEM results from the fact that the assessment of behaviour of the material in dynamic conditions is made based on the parameters that characterize the fruit of vegetable obtained in the conditions of quasi static conditions (Salarikia et al, 2017;Gao et al, 2018;Nikara et al, 2020).…”

The article presents determination methods of characteristic values of the reaction force course during the impact on fruit and vegetables to quickly assess their firmness or maturity. Moreover, various methods of modelling of the plant material behaviour during the impact that use differential equations, analytical equations, statistic models and numerical methods were discussed. Furthermore, dynamic methods that use fruit dropping on a rigid plate and measurement techniques that use a rigid element that hits a motionless fruit were reviewed and assessed. Advantages and disadvantages of these methods were presented. Statistical models are better for assessment of the bruise damage, but theoretical models are more useful for understanding the impact of various factors related to the impact damage. Various methods of application of rheological theories that describe a behaviour of the produce tissue treated as an elastic, elastic and plastic and visco-elastic were also described.

“…Recently, Nikara et al (2020) developed a geometrical model which comprised of a set of potato cells in a FE modelling environment to investigate micro-mechanical changes in the tissue and cells in response to impact load. In the study, scanning electron microscopy technique was adapted for the better representation of the geometrical model comprised of cells and tissues of the potato.…”

“…With the combination of sophisticated image processing technique, it is possible to quantify the external and internal damage in FV (Yousefi et al, 2016;Celik 2017). By means of the scanning electron microscopy (SEM) technique, Nikara et al (2020) estimated damage area by measuring section area, perimeter, and the roundness of the impacted potato cell. The relation between cell parameters can be described based on the following Equation 5𝑅 𝑐 = (4𝜋 𝑥 𝐴 𝐶 ) 𝑃 𝐶…”

Fresh agricultural products are very susceptible to physical damage resulted from the mechanical impact during post-harvest operations such as packaging, storing and transporting. Defects produce are prone to cellular damage that can then serve as infection sites for numerous wound pathogens that result in much of the postharvest diseases This paper reviewed the applicability of finite element modelling (FEM) for predicting the damage in fruits and root vegetables (FV) during the condition of static and dynamic loadings. However, many unresolved issues that need to be addressed to improve the finite element (FE) models. This work aims to provide readers with background information regarding the current state of FEM in predicting the mechanical damage in FV. A brief description of the relation between the reverse engineering approach, mechanical tests and FE method is discussed. The improvements to experimental validation techniques which allow for better-calibrated models are also explained. This article presents the recent developments in FEM, highlighting the applications and its contributions to the agricultural field as well as identifying open issues where extensive research is needed.
