Abstract For energy scavenging applications, estimating fatigue life of dielectric elastomer is as crucial as computing the amount of scavenged energy. Crack growth approach, well known in rubber industry, is a fast methodology to estimate fatigue life. We adapt this methodology to dielectric silicone elastomers (Elastosil 2030) and we focus in particular on the factors influencing this estimation such as sample geometry, tearing energy, power law. We underline that the variation in tearing energy estimation induces a small dispersion on the fatigue life estimation whereas power law identification is the crucial and critical parameter. Finally, we define an index of performance based on fatigue life and scavenged energy density, and we compare two materials (acrylic 3MVHB4910 and silicone Elastosil 2030).

影响介电弹性体发生器疲劳寿命预测的参数

摘要 对于能量清除应用，估计介电弹性体的疲劳寿命与计算清除能量一样重要。橡胶工业中众所周知的裂纹扩展方法是一种估算疲劳寿命的快速方法。我们将这种方法应用于介电有机硅弹性体 (Elastosil 2030)，我们特别关注影响这种估计的因素，例如样品几何形状、撕裂能、幂律。我们强调撕裂能量估计的变化会导致疲劳寿命估计的小偏差，而幂律识别是关键和关键的参数。最后，我们根据疲劳寿命和清除能量密度定义了一个性能指标，并比较了两种材料（丙烯酸 3MVHB4910 和硅胶 Elastosil 2030）。
