Evaluating and Improving Locomotive Crashworthiness Using LS-DYNA

Rail Transportation, 2000
Abstract Representative structural models of locomotives, other rail vehicles, and other potential colliding objects were combined into moving consists which were then subjected to various collision scenarios. The LS-DYNA dynamic finite-element modeling code was utilized to realistically simulate collisions and guide understanding and ...

The using of LS-DYNA for the simulation of heat transfer in explosives

Journal of Computer-Aided Materials Design, 2007
The using of FEM and especially LS-DYNA3D code for the simulation of a heat transfer during the heating of the explosive charge is discussed in this paper. The characterization of explosive material properties (density, thermal conductivity, specific heat, heat of decomposition, the decomposition kinetics) is described.

Numerical Simulation of Dynamic Compaction Using Ls-Dyna

2008
In the process of dynamic compaction, large deformation occurs at some rammed points and their surrounding areas. In this paper, the vibration of dynamic compaction is analyzed with the large deformation theory and LS-DYNA finite element software is employed to simulation the process of dynamic compaction.

The Masonry Crack Propagation Simulation Based on LS-DYNA

Advanced Materials Research, 2014
Due to the development of the computer hardware and the difficulties in determining the constitutive relation, it is difficult to research the crack propagation of large-scale masonry with the finite elements analysis method. The paper analyses the single storey concrete block masonry experimental model with the software LS-DYNA, using winfrith ...

Manual interface LS-Dyna and MATLAB

2010
The goal of this manual is to give an introduction to build a data interface between the finite elements software LS-Dyna and the numerical computing environment MATLAB. A case study is used to illustrate the working principle of this interface. In this case study the dynamic behaviour of aluminium plates subjected to close range blast loads is ...
