Numerical Investigation of Structural Response of Corrugated Blast Wall Depending on Blast Load Pulse Shapes
Hydrocarbon explosions are one of most hazardous events for workers on offshore platforms. To protect structures against explosion loads, corrugated blast walls are typically installed. However, the profiles of real explosion loads are quite different depending on the congestion and confinement of Topside structures. As the level of congestion and confinement increases, the explosion load incre...
متن کاملStructural Response of Offshore Plants to Risk-Based Blast Load
Offshore oil and gas process plants are exposed to hazardous accidents such as explosion and fire, so that the structural components should resist such accidental loads. Given the possibilities of thousands of different scenarios for the occurrence of an accidental hazard, the best way to predict a reasonable size of a specific accidental load would be the employment of a probabilistic approach...
متن کاملNumerical Investigation of Circular Plates Deformation under Air Blast Wave
In the current research the maximum deflection of circular plates made of AA5010 and AA1100 alloys under blast load was investigated. Shock waves were produced by exploding a spherical charge in different distances from the center of plates. The ABAQUS software uses conwep equation for blast loading analysis. It was found the results of these simulations have about 30% to 40% inaccuracy in comp...
متن کاملblast loading and evaluation of nonlinear response of structural buildings
in the conditions in which terrorist attacks on facilities and civilian places increase more and more attention to design of structures against impact loads of explosion is more important and needs special considerations. study of nature of blast loads and methods of applying it on the structure is one of the important problems. explosion is a sudden and rapid release of a great amount of energ...
متن کاملNumerical modeling of primary thoracic trauma because of blast
Purpose: Since explosive blasts continue to cause casualties in both civil and military environments, there is a need for an understanding of the mechanisms of blast trauma at the human organ level, plus a more detailed predictive methodology. The primary goal of this research was to develop a finite element model capable of predicting primary blast injury to the lung so as to assist in the d...
