摘　　要：粘弹性材料在简谐干扰输入下的椭圆形应力应变关系较为复杂。为了简化计算,介绍一种将椭圆形应力应变关系进行"廋"身的方法,并结合曲线拟合经验,提出粘弹性材料应力应变常数的简化计算公式。Viscoelastic damper can effectively reduce the response to structure because of the wind vibration and earthquake; it is a very important link to determine the stress-strain relationship of viscoelastic materials. The stress-strain relationship of viscoelastic materials for harmonic dry scratching input oval is relatively complex. In order to simplify the calculation, this paper introduces a kind of method to simplify the oval stress-strain relationship. Combining with curve fitting experience, it presents viscoelastic materials stress-strain constant simplified calculative formula.
