    • Methods are presented for modifying a physical property of a structure, such as reducing or relieving remaining internal stress, in which two or more energy types are concurrently applied to the structure to change the physical property of interest in an accelerated fashion. A first energy type, such as heat, is applied according to time values and operational settings derived from a first order rate relationship for the first energy type and from a first order rate relationship for a second energy type. The second energy type, such as vibration or other time-varying energy form, is applied concurrently for the time value. Methods are also provided for determining operational settings for concurrent application of multiple energy types to a structure.
    • 提出了用于修改结构的物理性质的方法,例如减少或减轻剩余的内部应力,其中两个或多个能量类型同时施加到结构以以加速的方式改变感兴趣的物理性质。 根据从第一能量类型的一阶速率关系导出的时间值和操作设置以及针对第二能量类型的一阶速率关系来应用第一能量类型,例如热量。 时间值同时应用第二种能量类型,例如振动或其他随时间变化的能量形式。 还提供了用于确定将多种能量类型并行应用于结构的操作设置的方法。
