In the second part, thinking of the fact that ship girders with special holes in web are commonly used, the author studied the stress concentration of this kind of structures by using fem and discussed the influence of hole to overall structural strength and its reinforcing methods
本文的第二部分針對船舶強梁腹板特殊開孔的工程實際,應用有限元法分析了開孔引起的應力集中現象和開孔后對強梁整體強度的影響,討論了工程開孔三種常用補強方法的補強效果。 -
Internal waves are a kind of bridge relating the diapycnal mechanical mixing to external sources of mechanical energy : first, internal waves are driven by wind stress and barotropic tide so that large amount of mechanical energy are transported to abyssal ocean with propagation of internal waves ; second, the mechanical energy can directly be cascaded to mixing through instability and breaking of internal waves
內波是外界提供的機械能與混合之間聯系的橋梁之一,一方面風和潮汐通過激發內波,將能量向深海和大洋內區傳遞,另一方面,內波的不穩定和破碎直接將機械能串級到小尺度湍流混合中去。開展傾斜地形上內波的傳播以及內潮的產生等方面的研究對海洋混合過程的參數化以及混合對大洋環流的影響等方面的研究具有重要的科學意義。 -
The second kind of degradation failure of random failure standard is the stress - strength interference failure considering stochastic stress and strength aging degradation
在加速退化方程和加速退化因子概念的基礎上給出了幾種典型退化失效 -
