It is a very important task to construct life-saving passage in building ruins rapidly and scientifically the process of earthquake rescue. Currently, virtual scene built train rescuers quickly scientifically. However, there are problems such as high cost, small quantity, single form. A new method constructing was proposed based on combined finite element (FE) finite-discrete (F-DE) restarted f...

In this paper, results are presented of non-linear finite element simulations performed to investigate the effects of varying the geometry of slotted tubes (stent) using finite element method. The analyses were performed using finite element packages LS-DYNA explicit solver for solution of the problem and ANSYS (Version 5.7) as preand post-processor. The analyses involved five different designs...

Sandwich tube structures bio-mimicking horsetail and human tendons offered significant improvement over traditional single multi-cell tubular energy absorbers. The present research aims to investigate three manufactured hybrid aluminum GFRP sandwich tubes subjected quasi-static low-velocity axial compression. crashworthiness characteristics crushing failure mechanisms of are discussed compared ...

This study investigates the lateral impact responses of reinforced concrete (RC) and composite columns through dynamic nonlinear analysis using LS-DYNA. The simulation results were first validated against experimental performed earlier on four different cross sections. finite element show that LS-DYNA can predict well be used for further parametric analysis. overall resistance new is significan...

Scalable Implementation of Finite Elements by NASA (ScIFEN) is a parallel finite element analysis code written in C++. ScIFEN is designed to provide scalable solutions to computational mechanics problems. It supports a variety of finite element types, nonlinear material models, and boundary conditions. This report provides an overview of ScIFEi (“Sci-Fi”), the implicit solid mechanics driver wi...

The accurate prediction of the spring back has great significance to the cold bending of plates. Based on the analysis of the square non pressure head CNC bending machine forming principle, the finite element model of the cold forming of the hull plate surface was established using the ANSYS/LS-DYNA finite element software. And the spring back computing research was done on the thickness of 8 m...
