Introduction In various processes including plastic deformation of materials as well as in sheet metal forming the formation and evolution of dislocation microstructure influences the material response considerably.
The material parameters are E = 210 GPa, ν = 0.33, As = 52.5 kN, and An = 10.5 kN.

Introduction The human bones are the organic/inorganic composite materials, which is composed of hydroxyapatite (HAP) and protein with nanometer sizes.
Poor mechanical properties of pure HAP materials such as the lower strength and tenacity would lead to the problems of loosening, transferring and fracture for the materials implanted in vivo [1,2].
Experimental Materials Antheraea pernyi cocoon came from Henan province, China.
