It can sometimes be difficult to determine whether vehicles damaged by blast loading are repairable in theatre or so significantly damaged that the hulls must be scrapped. The primary purpose of this investigation is to provide basic metallurgical data to assist in determining the criteria of failure. On top of this, it may be possible that blast loading may actually improve the performance of ...
This paper aims to study the numerical behavior of concrete slabs reinforced with perforated steel plates (PSPs) through nonlinear finite element (FE) analysis performed by ABAQUS. In this regard, conventional steel rebars (CSRs) are replaced with (PSPs) in the concrete slabs. Due to the particular geometry that the configuration of the hole provides, these PSPs are more integrated with surroun...
This paper presents the development and experimental validation of a multi-hazard bridge pier concept, i.e., a bridge pier system capable of providing an adequate level of protection against collapse under seismic and blast loading. A multi-column pier-bent with concrete-filled steel tube (CFST) columns is the proposed concept, and the adequacy of this system is experimentally and analytically ...
The columns of frame structures are the key load-bearing components and the exterior columns are susceptible to attack in terrorist blasts. When subjected to blast loads, the columns would suffer a loss of bearing capacity to a certain extent due to the damage imparted which may lead to their collapse and even cause the progressive collapse of the whole structure . The concrete-filled steel col...
The Basic Local Alignment Search Tool (BLAST) website at the National Center for Biotechnology (NCBI) is an important resource for searching and aligning sequences. A new BLAST report allows faster loading of alignments, adds navigation aids, allows easy downloading of subject sequences and reports and has improved usability. Here, we describe these improvements to the BLAST report, discuss des...
Purpose: Blast-induced traumatic brain injury (bTBI) is one of the causes of death or permanent invalidity which can occur unexpectedly in both military and civilian populations. This study set out to conduct a combined Eulerian-Lagrangian computational analysis of the interaction between a single planar blast wave and a human head in order to assess the extent of intracranial shock w...
Evaluation and Comparison of Behavior of Steel Jacketed RC Columns with Circular and Square Sections under Blast Loading Reinforced concrete (RC) structures are widely used in urban buildings and infrastructures, and these are always subjected to explosions caused by intentional or unintentional accidents. Among the structural members, columns are key load carrier elements. In this paper, b...
“Cold-formed steel (CFS) stud walls” are innovative alternative for construction of walls in buildings. The main frames of CFS walls consist of a group of vertical members called “studs” which are hold by fasteners within two horizontal members called “tracks” at the upper and lower ends. One of the conventional ways for designing and analyzing of CFS stud walls under blast loading is to employ...
Traumatic brain injuries have recently been put under the spotlight as one of the most important causes of accidental brain dysfunctions. Significant experimental and modeling efforts are thus underway to study the associated biological, mechanical and physical mechanisms. In the field of cell mechanics, progress is also being made at the experimental and modeling levels to better characterize ...
