Exact Solution of a Cylinder Tube Made of Metallic Foam Under Inner Pressure

Exact solution of the stress and velocity fields of a cylinder tube of metallic foams under inner Pressure is given in which the Triantafillou and Gibson constitutive law(TG model)for the material is taken as a basis of the calculation.The nonlinear equation is turned linear equation by introducing a kinematics parameter.The differences between the full condensed materials and the effect of the relative densitv are also discussed.
