摘要

主要介绍了国内外研究PVB（聚乙烯醇缩丁醛）材性的现状。国内外研究表明，PVB是应变率及温度敏感材料。应变率增加，弹性模量变大；温度升高，弹性模量和剪切模量均下降。同时，国内外进行了少量的实验，研究PVB的本构模型。总结发现，PVB的本构模型可描述为线弹性、弹塑性、线性粘弹性和非线性粘弹性四种，但本质上PVB是非线性粘弹性材料，不同的环境条件与计算要求可选择不同的本构模型。目前，国内外学者比较认可的是用超弹性考虑其非线性，用Maxwell模型考虑其粘弹性。

Abstract

This paper mainly introduces the status quo of researching on PVB (Polyvinyl Butyral) material properties at home and abroad. It shows that PVB is strain rate dependence and temperature sensitivity material. While strain rate increasing

elastic modulus will larger; While temperature increasing

elastic modulus and shear modulus decreased. Meanwhile

there are few experiments at home and abroad researching on the constitutive model of PVB. In general

PVB can be described as four constitutive models: linear elastic

elastic-plastic

linear viscoelastic and non-linear viscoelastic

but essentially PVB is non-linear viscoelastic materials. Different environmental conditions and computing requirements should choose different constitutive model. At present

scholars both domestic and oversea recognize using hyperelastic to consider the nonlinear

and considering the viscoelastic by a Generalised Maxwell Series.
