Current Navy implementation of statutory requirements for naval surface combatants dictates the performance of a ship shock trial in order to determine the vulnerability of a ship to an underwater explosion (UNDEX) non-contact shock threat environment. The shock trial features a series of shots, typically three to four, at increasing levels of severity culminating in a two-thirds ship design le...

Abstract Shock‐lithification is a fundamental process of making rocks from fine‐grained and porous regoliths on the surface Moon. Previous investigations have constrained potential shock pressures during shock‐lithification based experimental numerical simulations. However, pressure temperature conditions not been directly inferred natural lunar breccias. Here, we report discovery widespread ti...

To appear in: Archive for Rat. Mechanics and Analysis Consider the Cauchy problem for a system of viscous conservation laws with a solution consisting of a thin, viscous shock layer connecting smooth regions. We expect the time dependent behavior of such a solution to involve two processes. One process consists of the large scale evolution of the solution. This process is well modeled by the co...

in this paper we investigate the effect of oil price shocks on stock market index in iran, by using of a structural var (svar) approach. we used four variables in the model namely kilian index, global oil supply, real oil price and real stock market index. the data are monthly and spanning the period 1997m10-2014m12. we identify the effect of four different shocks on stock market including oil ...

Thermal X-ray emission which is simultaneous with the prompt gamma-rays has been detected for the first time from a supernova connected with a gamma-ray burst (GRB), namely GRB060218/SN2006aj. It has been interpreted as arising from the breakout of a mildly relativistic, radiation-dominated shock from a dense stellar wind surrounding the progenitor star. There is also evidence for the presence ...

The application of adhesively bonded joints in aerospace structural parts has increased significantly recent years and the general advantages their use are well-documented. One disadvantages adhesive bonding is relevant permanence, when compared to traditional mechanical fastening. End-of-life processes generally require separation adherents for repair or recycling, usually achieve this, they c...
