Summary
The elastic modulus of wheat grains, crucial for mechanical analysis and 3D modeling, ranges from 37 to 75 MPa as moisture content increases from 10% to 20%. This study validated these findings using a 3D model, showing less than 5% difference in compressive deformation.
Area of Science:
- Agricultural Engineering
- Materials Science
- Biophysics
Background:
- The elastic modulus (E) is a critical mechanical property of wheat grains.
- It is essential for accurate three-dimensional (3D) modeling and material analysis of wheat.
- Understanding E's relationship with moisture content is vital for grain handling and processing.
Purpose of the Study:
- To investigate the relationship between load-deformation properties and pressures in wheat grains.
- To determine the elastic modulus (E) of wheat at different moisture contents.
- To validate and amend the calculated elastic modulus using a 3D model.
Main Methods:
- Wheat grains with three different moisture contents (10-20%) were analyzed using a TA-XT2i texturometer.
- Load-deformation data was collected to calculate the elastic modulus (E).
- A 3D model was employed to verify and refine the elastic modulus calculations.
Main Results:
- The elastic modulus (E) of wheat grains ranged from 37 to 75 MPa.
- This range correlated with a rise in moisture content from 10% to 20%.
- The 3D model demonstrated a compressive deformation difference of less than 5% compared to experimental results.
Conclusions:
- The elastic modulus of wheat is significantly influenced by moisture content.
- The study successfully determined the elastic modulus range for wheat under varying moisture conditions.
- The validated 3D model provides a reliable tool for analyzing wheat's mechanical properties.

9.3K
The quantity that describes the deformation of a body under stress is known as strain. Strain is given as a fractional change in either length, volume, or geometry under tensile, volume (also known as bulk), or shear stress, respectively, and is a dimensionless quantity. The strain experienced by a body under tensile or compressive stress is called tensile or compressive strain, respectively. In contrast, the strain experienced under bulk stress and shear stress is known as volume and shear...

In analyzing a structural member composed of two different materials with identical cross-sectional areas, it is crucial to understand how their distinct elastic properties affect the member's response under load. The analysis involves assessing stress and strain distributions using the transformed section concept, which accounts for variations in material properties.

745
Deformation occurs in axial and transverse directions when an axial load is applied to a slender bar. This deformation impacts the cubic element within the bar, transforming it into either a rectangular parallelepiped or a rhombus, contingent on its orientation. This transformation process induces shearing strain. Axial loading elicits both shearing and normal strains. Applying an axial load instigates equal normal and shearing stresses on elements oriented at a 45° angle to the load axis.

Indeterminate structures refer to structures where internal forces and reactions cannot be determined using only the equations of static equilibrium. Indeterminate structures have more unknown forces and reaction forces than equations of static equilibrium that can be used to determine them. Indeterminate structures are often used in engineering to create complex, efficient, and aesthetically pleasing structures. There are various types of indeterminate structures used in engineering and...

Understanding the strain energy density in materials under axial load is crucial for evaluating their mechanical behavior and durability. When a rod is subjected to such a load, it elongates and stores energy, known as strain energy, as potential energy within the material. This energy is measured in terms of energy per unit volume.
