“…Determination of the constitutive model is vital for the success of FE simulation. From force-deformation curve data, the obtained elastic constant indicated a linear force-deformation curve, and the values of failure stress satisfy the bioyield point, which indicates the beginning of rupture [ 15 ]. The tangent modulus also related to the deformation behaviour, which was associated with the slope of the force-deformation curve.…”

“…In addition, the effect of temperature was neglected during the simulation. Besides, the analysis-setting function in ANSYS also included the hourglass control, viscous damping, reduced integration, distortion control, and erosion dynamic mesh, which were used to maintain the model accuracy [ 15 ].…”

“…With advances in numerical method and computer simulation, finite element method (FEM) has been used to solve the mechanical-based problems that fruits encounter during quasi-static and dynamic loadings [ 11 , 12 ]. Several studies have been conducted on FE modelling and simulation analysis of fruits under biaxial tension-compression [ 13 , 14 ] and drop tests [ 15 , 16 ], but still, to this date, no FE-puncture model has been proposed.…”

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.

Restitution coefficient (RC) of garlic bulb is an important mechanical property that is required to establish the kinematics model of bulb collision and research the damage mechanism of bulb collision. In this study, kinetic equations of bulb collision were established based on Hertz's contact theory. The kinematics characteristics, elastoplastic deformation and contact damage during bulb collision were analyzed by using high-speed photography. The effects of bulb mass, moisture content, collision material, material thickness and release height on the RC were investigated by mixed orthogonal experiments and single-factor experiments. The results showed that the movement of bulb in the compression stage was translation, and the movement in the rebound stage was translation and rotation. During collision, the larger the rotational angular velocity of the bulb was, the smaller the measured RC would be. The contact damage of bulb included internal damage of the tissue, epidermis stretch and tear. The significance of effects of factors on RC decreased with the following sequence: collision material, release height, material thickness, bulb mass, and moisture content. Collision material, release height, material thickness, and bulb mass were significant factors. The RC between the bulb and Q235, nylon, and rubber decreased sequentially. The RC decreased with the increase of release height and bulb mass. The RC increased with the increase of material thickness of Q235, while it decreased with the increase of material thickness of rubber or Nylon. The determination coefficients of the regression equations between the significant factors and the RC were all greater than 0.96. The results will be helpful for damage mechanism analysis and design of garlic production equipment.

“…Many researchers investigate the correlation of bruising level to various mechanical factors such as force, drop height, impact velocity, and absorbed energy (Ahmadi et al, 2010;Jiménez et al, 2016;Jiménez-Jiménez et al, 2013;Yousefi et al, 2016;Zarifneshat et al, 2010). With the advancement of technology, some researchers suggested to use simulation method to predict the effect of impact such as bruising (Abedi & Ahmadi, 2014;Celik, 2017;Du et al, 2019;Kabas, 2010).…”

Mechanical damage of fruit is one of the consequences of inappropriate harvesting and postharvest process (Lu & Lu, 2017).Nowadays, the harvesting of agriculture products is mechanized by different harvesting machines and then transferred to food industry for postharvest operations (Komarnicki et al., 2017). The shape of damage depends on the physical and biological structure of the product as well as the type of load (static, dynamic, and oscillating).These occurrences sometimes damage the internal tissue of the fruit which not only spoils the fruit tissue but also leads to discharging the material of the inside cell and spreading damage (Li et al., 2017).Usually, bruising caused by the impact is not detectable immediately and depending on the flesh and biological characteristics of the fruit, it is observable after a few hours (Scheffler et al., 2018).On the other hand, the water and much carbohydrate content which contribute to the metabolic processes lead to an increasing bruised area. This damage of fruit's skin remains even after the fermentation
