It covers the mechanical properties of foams and foam microstructure, processing of foams, mechanical testing and analysis (using Finite element analysis). In addition, it uniquely offers a broader perspective on the actual engineering of foams and foam based (or foam including) products by including nine detailed 606 $aPlastic foams 606 $aFoamed materials 615 0$aPlastic foams. 615 0$aFoamed materials. 676 $a668.4/93 676 $a668.493 700 $aMills$b N.
