In this paper, numerical simulation of FRP composite cylinder tubes progressive crushing processes is conducted using LS-Dyna. Details on the numerical modeling strategy are given and discussed. It is found that triggers introduced in the numerical simulation can effectively model the bevel trigger at the end of the tubular specimens. It is also found that two-layer finite element model based o...

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...

Reduced web section beams in shear-yielding moment-resistant steel frames are used for energy dissipating of earthquakes. The finite element analysis indicates that failure mode of these beams are governed by the combination of shear force and flexural moment. Therefore the analysis of frames with reduced web section beams needs consideration of shear-flexural interaction in those sections. In ...
