ON THE COUSTITUTIVE RELATION FORMS OF VISCOELASTIC MATERIAL IN VIBRATION ANALYSIS OF COMPLEX STRUCTURES
Chen Qian Zhu Demao
It must be concerned with the forms of coustitutive relation of viscoelastio materials in analizing the dynamio behaviour of elastic viscoelastic composite structures. This paper compares two constitutive relation forms, standard form and fractional derivative form, in aspects of eurve fitting of mechanic properties of viscoelastic material and the composite structural vibration analysis. It is considered that adopting standard form will be much more convenient than fractional derivstive form in vibration analysis.
