摘要:
针对粘弹性橡胶材料检测滞后性的问题,首先构建粘弹性橡胶材料的力学性能本构模型,得到该材料蠕变以及应力松弛过程中应力、应变及时间之间关系的数学表达式,再结合粘弹性橡胶材料制作的哑铃试件模型,利用COMSOL Multiphysics仿真软件仿真哑铃试件的蠕变以及应力松弛过程,得到哑铃试件各个状态下应力-应变分布状况以及应力应变随时间的变化关系,最后根据蠕变与应力松弛过程中的稳定状态,提出粘弹性橡胶材料拉伸过程中滞后性表征函数。
Abstract:
In light of the delay in detecting the viscoelastic rubber materials, the mechanical properties constitutive model of viscoelastic rubber material is first constructed by theoretical calculation, and the mathematical expression of the relationship between stress, strain and time in the creep and stress relaxation process of the material is obtained. The dumbbell test made by combining viscoelastic rubber material is used to simulate the creep and stress relaxation process of dumbbell specimens by COMSOL Multiphysics simulation software. The stress and strain distribution of the dumbbell specimens under various conditions and the relationship between stress and strain with time are achieved. Finally, the concept of relative stability state and the hysteresis characterization function of the viscoelastic rubber material during stretching are proposed according to the steady state in the creep and stress relaxation process. It is expected to provide a theoretical basis for the accurate measurement of the mechanical properties of viscoelastic rubber materials.
