- 中文摘要: 本文所論,為一非均勻剛度自由樑承受端頭推力之動力穩定問題。設想非均勻剛度可表成冪式,此等樑受定值推力及脈動推力時之情形,分別討論於本文第一部份及第二部份中。在此兩部份中,有關之動力穩定準則均於焉建立,並將數字結果表成圖形,以供實用。
- 英文摘要: The dynamic stability of a free-free beam or rod with nonhomogeneousflexural rigidity under end thrusts is investigated in this report. The nonhomogenity is considered to be in a general power law form.Such a beam under constant and pulsating thrusts are discussed respectivelyin Part I and Part II of this paper. In both parts, criteria for dynamicstability are established and the numerical results are presented in graphsfor pratical use.
