Including both the different strength in tension and compression and the contribution of intermediate principal shear stress on the material strength, the unified solution for sheet forming is gained based on Yu’s unified strength theory, which can be reasonably applied to a wide range of materials.
(3) where, st is the tensile ultimate strength of material, sc the compressive ultimate strength, to the shear ultimate strength, a the tension-compression-ratio, varying from 0.77 to 1.0 for ductile metal material, 0.33 to 0.77 for brittle metal material, and generally less than 0.5 for geotechnical materials, B tension shear ratio, and b participation factor of intermediate principal shear stress.

Numerous experiments have been performed with respect to the moisture sorption isotherms of food and agricultural materials, such as pumpkin[6] and so on.
Materials and methods Materials Salted, semidry largehead hairtail (Trichiurus lepturus) was purchased from an aquatic processing factory in Guangdong, China.
To prevent spoilage of the materials at water activities greater than 0.70, a small amount of toluene was added to a weighing bottle in the desiccator [11].
Rockland (1969) highlighted that materials rich in fat and protein show gradually sloping isotherms at a low relative humidity.
Consequently, this phenomenon decreases the water-holding capacity of the materials upon subsequent adsorption.
