“…The results confirmed that a larger displacement leads to an increase in the stress inside the fruit, and the stress distribution area also expands as the compression displacement increases. Similar results can be obtained for cantaloupe (Seyedabadi et al, 2015) and grapefruit (Ashtiani et al, 2019). Due to the large contact area between the R. roxburghii fruit and the flat plates under the vertical compressive load, the stress is mainly concentrated in the ring shape of the cavity surface inside the fruit.…”

“…The results showed that the internal structure and compressed position of the fruit have a significant impact on its mechanical properties and the deformation of four locular tomatoes compressed at a position midway between adjacent cross walls was the largest. Seyedabadi, Khojastehpour, and Sadrnia (2015) developed a nonlinear finite element model of cantaloupe to predict the maximum load of mechanical damage to the fruit under compressive load. Through compression tests, they concluded that the correlation coefficient between the force obtained from the experimental results and the predictive force of the finite element models reached 0.983, which indicates that the finite element model can predict the internal damage of cantaloupes.…”

It is very necessary to understand the mechanical properties of Rosa roxburghii fruit for harvesting, packaging, processing, transportation, storage, and related equipment design and improvement. This research was to determine the mechanical properties of R. roxburghii fruits through compressive experiments and finite element simulations and to verify the accuracy of the finite element model. In order to achieve finite element analysis, an accurate three-dimensional (3D) geometric model was reconstructed by applying 3D laser technology and point cloud reconstruction algorithm. The elastic modulus and Poisson's ratio of R. roxburghii fruits were determined to be 4.0 MPa and 0.35 through experiments. The finite element simulation results provided valuable numerical data and visualized stress distribution. The simulation results showed that R. roxburghii fruits were damaged under the loads of 156.2 N (vertical) or 148.3 N (horizontal), with a maximum deformation of 5.0 mm (vertical) or 6.93 mm (horizontal), respectively. In the vertical and horizontal compression posi-

“…The finite element method (FEM) as a numerical technique is available to accurately solve complex engineering problems that are not solvable by analytical methods or require costly experiments to arrive at an acceptable solution. [27] By accounting the shrinkage in the heat and mass transfer equations, the resulting systems of coupled nonlinear PDEs must be solved under the moving boundary conditions. This problem can be solved by FEM coupled to the Arbitrary Lagrangian-Eulerian (ALE) procedure.…”

The finite element method was employed to model the simultaneous heat and mass transfer in cylindrical samples of banana during convective drying. The Arbitrary Lagrangian-Eulerian (ALE) approach was implemented to incorporate the axial and radial shrinkage effects in the FEM model. The results showed that the FEM model was satisfactorily able to predict the moisture content (R 2 > 0.97) and core temperature (R 2 > 0.98). Therefore, the proposed model can be used as a promising tool to optimise the drying process of banana from quality and efficiency points of view. Also, the model can be easily extended for drying of similar products with cylindrical shape. ARTICLE HISTORY

“…Experimental studies on cantaloupe damage reveal that internal contusion damage occurs when the total deformation is approximately 20%. The finite element method is used for prediction, and the correlation between the predicted and measured values is high, which proves that the finite element method can be used to predict the internal bruise damage of cantaloupe [23]. Drop mechanical properties of pears with different maturities can be determined by a combination of experiments and finite element simulation, and the bruised area of pears can be effectively predicted [24].…”

Bruising of the subcutaneous tissues of blueberries is an important form of mechanical damage. Different levels of bruising have a significant effect on the post-harvest marketing of blueberries. To distinguish different grades of blueberry bruises and explore the effects of different factors, explicit dynamic simulation and near-infrared hyperspectral reflectance imaging were employed without harming the blueberries in this study. Based on the results of the compression experiment, an explicit dynamic simulation of blueberries was performed to measure the potential locations of bruises and preliminarily divide the bruise stages. A near-infrared hyperspectral reflectance imaging system was used to detect the actual blueberry bruises. According to the blueberry photos taken by the near-infrared hyperspectral reflectance imaging system, the actual bruise rates of blueberries were obtained by using the Environment for Visualizing Images software for training and classification. Bruise grades of blueberries were divided accordingly. Response surface methodology was used to determine the effects of ripeness, loading speed and loading location on the blueberry bruising rate. Under the optimized parameters, the actual damage rate of blueberries was 1.1%. The results provide an important theoretical basis for the accurate and rapid identification and classification of blueberry bruise damage.
