Abstract:	摘要　　　　　　當材料承受動力荷載時，會使材料中的孔洞產生震動，而微孔震動的情形，可能受外力強度、頻率、種類等因素的影響。本篇論文延續前人對於材料受動態荷載作用下孔洞震動情形的研究成果。對各種不同種類的外力作用下微孔的振動進行探討，找尋不同種類外力作用下微孔震動型態的相似之處。除此之外，論文中也探討微孔的初始孔徑改變之下，頻譜圖是否跟著改變且有特定的趨勢。 Abstract When a material is subjected to dynamic loads, the micro void in the material will vibrate.The vibration may be affected by the intensity, frequency and type of the external load and so on. This thesis extends the previous research for the vibration of a cavity in a material which is subjected to dynamic loads. We study different types of micro-void vibrations which are induced by different external forces and look for the similarities between these vibrations. In addition, we also investigate whether the response spectrums change or not when the initial diameter of the micro- void changes.
