The objective of this proposal is to conduct a preliminary analytical/experimental investigation on the effects of solitons in solid materials. Soliton is a single isolated wave pulse which propagates at a constant velocity without change in shape or amplitude in a nonlinear elastic medium. Since its discovery in 1834, it has been studied theoretically but to date it has never been recorded experimentally in solids. This is an Expedited Award for Novel Research in which the PIs will attempt to detect the solitons indirectly by impacting a one dimensional sandwich model which is fabricated with alternating metal and rubber plates. Successive spallation of the metal plates will be an indirect and simple evidence of the existence of solitons. In addition to its academic interest, this soliton study will provide an insight to the dynamic fracture of elastomeric spring and in the design of shock isolation devices.

本提案的目的是进行初步的 中孤立子效应的分析/实验研究 固体材料。 孤子是一种孤立的波脉冲， 以恒定的速度传播而不改变形状， 非线性弹性介质中的振幅。 自从它在1999年被发现以来， 1834年，它被理论上研究过，但迄今为止还没有 在固体中实验记录。 这是一个快速奖， 新的研究，其中PI将尝试检测孤子 间接地通过冲击一维夹层模型， 由交替的金属和橡胶板制成。 连续 金属板的喷涂将是一种间接和简单的方法， 证明了孤子的存在。 除了其学术 有趣的是，这个孤子研究将提供一个动态的洞察力 弹性弹簧断裂和冲击隔离设计 装置.
