简介：为在受到飞机紧张条件的一个盘子中的一个中央裂缝的一个问题被调查。我击碎装载的模式被从裂缝在大距离使用的动态压力脉搏创造。为振幅的某个联合和使用的脉搏的持续时间，传给样品的能量有强烈显著的最小，这被发现，意味着与移动离开最佳的价值的脉搏振幅或持续时间，最小的能量为生长很快增加的快克的开始要求了。获得的结果显示优化不同工业过程的能量消费的可能性与骨折连接了。大部分能被获得在例如，钻或跳能量输入在哪儿说明这进程的最大的部分的岩石花费了。观察的效果的大概进一步的调查能使预言节省参数的最佳的能量可能，即为工业设备，例如讨厌的人，磨擦用机器制造的影响的频率和振幅，并且显著地因此减少过程费用。预言能基于折断的媒介的参数被给(材料参数，流行裂缝长度和取向，等等)。

简介：Jep积分为描绘有弹性塑料的材料的破裂行为被导出。Jep积分不同于米饭J积分因为工作的免费精力密度而非压力密度被采用定义精力动量张肌。Jep积分被证明不管增长粘性和变丑粘性是路径依赖者。Jep积分拥有清楚地清楚的物理意思：(1)在包围裂缝尖端的无穷地小的轮廓上评估的价值Jtipep代表裂缝尖端精力驱散；(2)当全球steadystate裂缝生长条件被接近时，沿着边界轮廓计算的Jfar-ssep的价值等于到裂缝尖端驱散和塑料地区的体积驱散的和。理论结果被模仿我击碎的模式验证问题。
