Catastrophic disturbances often provide "natural laboratories" that allow for greater understanding of ecological processes and response of natural populations. The 1980 eruption of the Mount St. Helens volcano in Washington, USA, provided a unique opportunity to test biotic effects of a large-scale stochastic disturbance, as well as the influence of post-disturbance management. Despite severe ...

In modern warfare, anti-vehicular mine attack is one of the critical consideration in the design of an armored personnel vehicle. Nowadays, the use of computational tools is a common approach in vehicle design process for evaluating the vehicle and its occupant’s safety or protective levels. This paper presents a finite element analysis carried out on the underbelly of SIBMAS AFSV 6x6 armored v...

The paper is concerned with the development of a fast, accurate, and versatile method of simulating the propagation of a blast wave within complex built environments. An ability to complete a simulation of the propagation of a blast wave within a few seconds or minutes is an essential tool for evaluating its impact on key structures and to find an optimal design for components such as blast bar...

The Garvin–Alterman–Loewenthal solution refers to the problem of a line blast load suddenly applied in the interior of an elastic half-space. It is expected that the long-time asymptotic limit of this solution should be equal to the solution of a related static problem. This expectation is justified here. First, the solution of the static problem is constructed. Then, the asymptotic limit of th...

At present, the drill-and-blast method is still one of main construction means in road tunnel excavation process. When penetrates underneath sensitive structures such as high-voltage transmission towers, blasting and supporting parameters must be strictly controlled to ensure stability safety surface structures. In this paper, numerical simulations based on a large-section shallow buried projec...

Blast-induced traumatic brain injury (TBI) has become a major issue as a consequence of deployment of military personnel under the Operation Iraqi Freedom (OIF) and Operation Enduring Freedom (OEF) in Iraq and Afghanistan, respectively. Threats during missions of the (Dutch) troops in these recent operations are not comparable with threats experienced formerly. They now have to deal with Improv...
