Numerical and Experimental Investigation of Deep Drawing of Sandwich Panels

Abstract:

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.
