Superplastically Formed New Sandwich Cores
Publication: Transportation Engineering Journal of ASCE
Volume 104, Issue 4
Abstract
A new method using superplastic materials and vacuum forming technique is developed. In this new process, different sandwich core configurations are obtained by heating up a superplastic sheet and then allowing it to collapse gently onto a die having the desired geometry. Two analytically investigated problems are reported: (1)Determination and maximization of the shear modulus of the core; and (2)least weight configuration analysis. Geometric shapes of four- and six-sided, truncated pyramids are presented. Advantages of this new innovation are cited.
