A multifactor optimization technique is used to define a multifunctional material that serves not only as a structural material but also as a sound and heat controlling material as well. The feasibility of satisfying certain structural, sound transmi

If ablative coatings are used to protect reentry vehicles under severe aerodynamic heating, why can they not be used to protect structural steel in fires? To answer this question, it is necessary to define ablation, to explore the nature of the therm
