“…[6,22] The Modulus of elasticity and Poisson's ratio obtained in this study have good compatibility with the results reported by Ref. [23] but observed some difference with Pallottino et al results which can be interpreted by different variety and therefore different texture of fruits. [17] The orange impact was considered and it was simulated through nonlinear FEM-based explicit dynamics simulation approach.…”

In this research, the behavior of orange fruit under impact cases was investigated by finite-element modeling in SolidWorks simulation and experimental dropping tests. The values of 0.584 MPa and 0.24 were experimentally determined for modulus of elasticity and Poisson's ratio as a pre-requirement for simulation. In the simulation tests, orange fruits were dropped from two different heights of 2 and 3 m with a drop angle of 45°r elatives to a rigid plane. Experimental tests were also conducted to validate simulation results. Maximum equivalent stress and contact force were obtained from simulation results 0.5826 MPa and 14.95 N, respectively.

This paper introduces an advanced engineering simulation procedure for the nonlinear finite element method (FEM) based high‐speed shattering case of shelled edible agricultural products. A high‐speed impactor which is targeted at the Pecan fruit (kernel‐in‐shell) was considered in this case study. Physical compression tests were conducted on Pecan fruit specimens and experimental deformation characteristics were utilized to describe realistic material models in the FEM based engineering simulation. Subsequently, a reverse engineering approach was employed in the solid modeling stage and the Pecan shell shattering case under high‐speed loading was simulated, considering the explicit dynamics approach. The effect of the high loading rate on the deformation characteristics of the Pecan fruit components was observed. Visual outputs from the simulation revealed the shattering behavior of the Pecan fruit components under defined boundary conditions. In addition to useful visual simulation outputs, time‐dependant stress distributions on the Pecan fruit under high‐speed loading rates were represented using graphs. Simulation results have revealed that maximum equivalent stress values were 7.1 (MPa), 5.1 (MPa), and 0.336 (MPa) for shell, packing material, and kernel, respectively. Maximum reaction force at impact was calculated as 996,000 (N). This work contributes to further research into the use of nonlinear numerical method based high‐speed deformation simulation studies for shelled edible agricultural products. Practical application As the industry relevance, useful deformation visuals and numerical findings related to impact shattering case of the Pecan fruit have been exhibited and the findings have been presented in a form which may be used as input parameters in design studies of shelled agricultural product processing machinery systems used in related industry.

“…1 DEC2000 (R). The compression test can express the relationship between axial loading force and deformation of the product and modulus of elasticity, which is an important property for determination of the stress distribution in agricultural products, and can be calculated using this relationship throughout elasticity theory (Blahovec, ; Ihueze & Mgbemena, ; Mohsenin, ; Shelef & Mohsenin, ; Sitkei, ; Stroshine, ).…”

This study, which is divided into two parts, introduces an explicit dynamics simulation procedure for Pecan fruit (Carya illinoinensis) deformation under compressive loading. An original application algorithm based on experimental and theoretical methods has been described in the study. The major aim of this Part 1 is to determine the modulus of elasticity through various calculation approaches for Pecan fruit. In addition to this, some engineering properties of the Pecan fruit components were determined to define them as simulation input parameters in an explicit dynamics deformation simulation which is detailed in the second part of the study. The original geometry of the Pecan fruit and its components were digitized using reverse engineering technology (three‐dimensional [3D] laser scanning). Force–deformation data, which can describe the physical deformation characteristics of the Pecan fruit components, was collected through experimental compression tests. Initial crack points for the Pecan shell (kernel‐in‐shell) in these tests were measured as 335.62, 239.42, and 165.03 N for longitudinal, transverse, and suture orientations, respectively. Hooke's, Hertz's, and Boussinesq's theories and finite element method simulation based linear prediction approach based modulus of elasticity calculations were realized. Results from these calculations revealed that loading orientation is an important factor and there were differences between the results of calculation theories (15.2% on average). Practical applications The simulation approach and application algorithm introduced in this two‐part study is a scientific novelty because the explicit dynamics simulation approach for Pecan fruit deformation has not previously been reported in the literature. This first part focuses on realistic description (digitizing) of the fruit geometry through a reverse engineering approach and determination of modulus of elasticity (by considering various theories) and some engineering properties of the Pecan fruit components (experimentally). These investigations have important roles in this study so that realistic material models of the fruit components can be described in the simulation study which is presented and detailed in the second part of the study. In this part, it has been experienced that loading orientation is an effective factor for fruit deformation behavior and different theories may provide different results during calculation of the specific mechanical properties. These important findings have been presented in a form which may be used as input parameters in design studies of shelled agricultural product processing machinery systems used in the related industry.
