assessment of the anisotropy effect when optimising the deep drawing process by numerical simulation

Commonly investigated problem on composite fabrication and forming for weight reduction in transportation and aerospace area is not completely cleared. The main difficulties on composites forming without building any defects caused new ways on process characterization due to the key parameters. In the paper two main problems were investigated, i.e. material fracture and material thinning during deep drawing. Through mechanical tests and numerical simulation the authors tried to couple the fracture with the technological boundary conditions of the deep drawing process and form a housing test part from a three-layer material.

In order to investigate the superplasticity of ceramic/ceramic laminated composite under tensile stress, the superplastic deep-drawing process was simulated by FEM. The results shown that, the strain and stress conditions of laminated composite, made by ceramic with different superplastic formability, are better than that of monolithic ceramic. Consequently, the material may exhibit high superplasticity. To testify this, some experiments were carried out. Tape casting and hot-press sintering are used to fabricate Al2O3/3Y-TZP laminated composite. As-received material is deep-drawing at high temperature to research its superplasticity. The results shown that, when suitable strain rate and forming temperature were used, the as-received material has excellent superplasticity.
