Experimental and finite element study on the spring back of double curved aluminum/polypropylene/aluminum sandwich sheet (original) (raw)

Materials & Design, 2010

Abstract

The most prominent feature of sheet material forming process is an elastic recovery phenomenon during unloading which leads to spring back and side wall curl. Metal–polymer laminate sheets are emerging materials that have many potential applications. Therefore evaluation of spring back is mandatory for production of precise products from these new sheet materials. In this paper, the results of spring
