Method for graphical presentation of the complex modulus of damping materialsWhat is BS 7544 Graphical presentation of damping materials about? BS 7544 discusses damping materials. The aim of BS 7544 is to improve communication among the diverse technological fields concerned with vibration damping materials. BS 7544 establishes the graphical presentation of the complex modulus of viscoelastic vibration damping materials which are macroscopically homogeneous, linear, and thermorheologically simple. The complex modulus may be
