Mechanical test of wheat.

No.	Type	Data	Conclusion	References
1	Triaxial test	15	The internal friction angle decreases with the increase of bulk density.	[16]
2	Triaxial test	36	The curvature variation of the molar strength envelope is explained.	[17]
3	Triaxial test	15	The estimated fourteen parameters were used in the constitutive equation to calculate stress-strain relationships for wheat en masse in axial compression and isotropic compression loading conditions.	[18]
4	Triaxial test	21	The shear rate has influence on shear strength, internal friction angle, and cohesion.	[20]
5	True triaxial tests	30	The mechanical properties of wheat flour and the change of curve were predicted by constitutive relation.	[21]
6	Uniaxial test	150	The three wheat varieties showed similar mechanical behaviors in the uniaxial compression test, but the breaking force value and average breaking energy were different.	[25]
7	Uniaxial test	16	The uniaxial compression test under small-strain conditions can be used to evaluate the viscoelastic properties of wheat grains of different grades and varieties.	[26]
8	Uniaxial test	18	The force-deformation curve has at least two inflection points, the first inflection point is the mechanical properties of the bran layer, and the second inflection point is related to the endosperm boundary near the aleurone layer.	[27]
