| 摘 要： | 运用粘弹性材料的积分型本构关系和应力波理论得出了粘弹性材料瞬态模量的计算式;又以丁苯橡胶作为试验材料设计了一种简便的试验方法,测出了丁苯橡胶的瞬态模量,并与丁苯橡胶的静态弹性模量做了对比。比较表明,丁苯橡胶类粘弹材料静态模量的值远低于瞬态模量值。

| Abstract: | The expression of instantaneous modulus was derived by using the integral constitutive relation and stress wave theory.A simple and convenient experimental method was designed with SBR as experimental material.Then the instantaneous modulus of SBR was measured and compared with the static modulus.The comparison shows that the static modulus of viscoelastic materical like SBR is rather lower than the instantaneous modulus. |
