Finite element analysis of damage accumulation for structure under impact

Finite element modeling of the human head under baton impact

Purpose: This research will try to predict damage probability and calculate the main stress resulted from baton impacts by finite element (FE) modeling of the human head considering skull texture, brain and cerebrospinal fluid.Materials and Methods: A three dimensional FE model of the skull-brain complex was constructed for simulating the baton impact. The FE analysis was carried out using ANSY...

Finite Element Analysis for CFST Columns under Blast Loading

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...

Experimental Study of Masonry Structure Under Impact Loading and Comparing it with Numerical Modeling Results via Finite Element Model Updating

Given the sophisticated nature of the blast phenomenon in relation to structures, it is of significance to accurately investigate the structure behavior under blast loads. Due to its rapid and transient nature, blast loading is one of the most important dynamic loadings on the structures. Since masonry materials are widely used as the partition and bearing walls in the existing and newly-built ...

APPLICATION OF FINITE ELEMENT MODEL UPDATING FOR DAMAGE ASSESSMENT OF SPACE STRUCTURE USING CHARGED SYSTEM SEARCH ALGORITHM

Damage assessment is one of the crucial topics in the operation of structures. Multiplicities of structural elements and joints are the main challenges about damage assessment of space structure. Vibration-based damage evaluation seems to be effective and useful for application in industrial conditions and the low-cost. A method is presented to detect and assess structural damages from changes ...
