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...
متن کاملFinite 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...
متن کاملExperimental 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 ...
متن کاملFinite Element Analysis of Helmeted Impacts and Head Injury Evaluation with a Commercial Road Helmet
This research was conducted to assess the safety performance of a commercial motorcycle helmet, homologated by the most relevant current standards and currently available in the market. The evaluation was based on accurate reproduction of translational impacts specified by the ECE R22.05 standard to assess motorcycle helmets. The Finite Element numerical framework was vali...
متن کاملFinite element method modelling of the properties of a Cu–SiC composite under cyclic loading conditions
The paper reports on finite element method (FEM) analysis of Cu–SiC composites behaviour under cyclic loading conditions. In order to emphasise the influence of materials description on following results, there were two hardening rules used to describe the plastic behaviour of the matrix: (a) simple isotropic and (b) combined isotropic-kinematic. Reinforcing ceramics was assumed to be perfectly...
