潜艇内部平台对舱壁支持作用的对比试验

为了研究平台对舱壁的支撑作用,针对以内部平台取代水平桁作为一级支持构件的潜艇平面舱壁结构形式,设计制作了两个平台强度不一样的舱段模型.然后,分别对两个模型进行静水压力试验,测量了其应力和承载能力.模型试验结果表明,平台的使用使舱壁的承载能力明显提高,且平台越强对舱壁的支持作用越大.平台结构的改变主要影响舱壁上垂向加强材上的应力水平,舱壁的破坏是由于平台受压失稳后失去对舱壁的支持引起的.

Nuclear weapons and alliance institutions in the era of President Trump

The swearing in of Donald Trump as the 45th President of the United States presages, at the very least, a period of flux in American strategy with respect to the relationship between nuclear weapons and alliances. In this response to three thoughtful rejoinders to our article, “Nuclear weapons, the United States and alliances in Europe and Asia: Toward an institutional perspective,” we clarify key aspects of our argument and discuss why alliance institutions are likely to be relatively robust in the face of change, how they can influence national decision-making, and argue that they may exert a moderating influence over the new administration.     

Indian Military Modernization and Conventional Deterrence in South Asia

In recent years, headline grabbing increases in the Indian defense budget have raised concerns that India’s on-going military modernization threatens to upset the delicate conventional military balance vis-à-vis Pakistan. Such an eventuality is taken as justification for Islamabad’s pursuit of tactical-nuclear weapons and other actions that have worrisome implications for strategic stability on the subcontinent. This article examines the prospects for Pakistan’s conventional deterrence in the near to medium term, and concludes that it is much better than the pessimists allege. A host of factors, including terrain, the favorable deployment of Pakistani forces, and a lack of strategic surprise in the most likely conflict scenarios, will mitigate whatever advantages India may be gaining through military modernization. Despite a growing technological edge in some areas, Indian policymakers cannot be confident that even a limited resort to military force would achieve a rapid result, which is an essential pre-condition for deterrence failure.     

Missile Strategy in a Post-Nuclear Age

While the arrival of nuclear weapons coincided roughly with the development of short, medium, intermediate, and eventually intercontinental missiles, the contribution of missile technology to the deterrence equation is often lost. If nuclear weapons were eliminated, even new generation missiles with conventional payloads could struggle to render effective deterrence. But some of the physical and psychological effects commonly ascribed to nuclear weapons could still be in play. And in a world without nuclear weapons, thinking about the use and control of force from the nuclear age would also deserve renewed attention.
