→ → LS-DYNA LS-DYNA LS-DYNA, developed by Livermore Software Technology Corp. (LSTC), is a multi-purpose explicit and implicit finite element program used to analyse the nonlinear response of structures. Its fully automated contact analysis and wide range of material models enable users worldwide to solve complex real world problems. Applications LS-DYNA is used by companies and universities worldwide to simulate a whole range of different engineering problems including;.
Product Testing. Drop Testing. High Velocity Impacts. Blast Loading. Biomedical. Staged Construction. Pore Water Pressure Consolidation Crashworthiness Simulation For many automotive companies LS-DYNA is a tool for understanding the deformation of complex systems such as vehicle structures.
The ability of LS-DYNA to model contacts and its wide range of material models make it ideally suited for this type of analysis. It also includes a number of specific features for automotive applications such as:. Spotweld Models. Airbag Models. Seatbelt System Models Occupant & Pedestrian Safety Analysis Providing crash protection for occupants and pedestrians is an integral part of modern vehicle development.
A range of fully validated FE models of the major physical test devices is available for LS-DYNA. These include:. Hybrid III 50th Percentile Male Dummy. Hybrid III 5th Percentile Female Dummy.
EuroSID-II Side Impact Dummy. US-SID Side Impact Dummy. SID-IIs Side Impact Dummy. Pedestrian Headform Impactors. Pedestrian Legform Impactors Metal Forming LS-DYNA has been used for sheet metal stamping since the late 1980's and can be used to assess a proposed forming process and tool design. Along with the forming process you can also simulate trimming and springback.
LS-DYNA has the capability to analyse a variety of different forming processes including:. Rigid Tool Stretch and Draw Forming.
Sheet and Tube Hydro Forming. Flex Forming.
Roll Forming. Superplastic Forming Drop Testing LS-DYNA has been used to simulate impact events of different containers for many years. Ranging from small electronic products such as mobile phones and laptop computers, up to large nuclear fuel containers. Features include:. Fluid Structure Coupling (ALE / SPH) for modelling liquid filled containers.
Element Free Galerkin (EFG) for modelling cracks. Explicit-Implicit switching for studying steady state deformation Seismic Analysis LS-DYNA provides engineers with a tool for modelling the complex nonlinear behaviour of a building during seismic events. Non-linear response history analysis can be performed using element types and functions including:. Lumped plasticity.
Fibre elements. Nonlinear dampers. Buckling elements. Frequency-dependent damping These features make LS-DYNA an ideal tool for engineers practising performance-based earthquake engineering.
About LS-DYNA is a general-purpose finite element program capable of simulating complex real world problems. It is used by the automobile, aerospace, construction, military, manufacturing, and bioengineering industries.
LS-DYNA is optimized for shared and distributed memory Unix, Linux, and Windows based, platforms, and it is fully QA'd by LSTC. The code's origins lie in highly nonlinear, transient dynamic finite element analysis using explicit time integration. 'Nonlinear' means at least one (and sometimes all) of the following complications:. Changing boundary conditions (such as contact between parts that changes over time). Large deformations (for example the crumpling of sheet metal parts). Nonlinear materials that do not exhibit ideally elastic behavior (for example thermoplastic polymers) 'Transient dynamic' means analyzing high speed, short duration events where inertial forces are important. Typical uses include:.
Automotive crash (deformation of chassis, airbag inflation, seatbelt tensioning). Explosions (underwater Naval mine, shaped charges). Manufacturing (sheet metal stamping) LS-DYNA's potential are numerous and can be tailored to many fields.

In a given simulation, any of LS-DYNA's many features can be combined to model a wide range of physical events. An example of a simulation, which involves a unique combination of features, is the NASA JPL Mars Pathfinder landing simulation which simulated the space probe's use of airbags to aid in its landing. LS-DYNA is one of the most flexible finite element analysis software packages available. LS-DYNA consists of a single executable file and is entirely command line driven.
Therefore all that is required to run LS-DYNA is a command shell, the executable, an input file, and enough free disk space to run the calculation. All input files are in simple ASCII format and thus can be prepared using any text editor.
Input files can also be prepared with the of a graphical preprocessor. There are many third party software products available for preprocessing LS-DYNA input files. LSTC also develops its own preprocessor, LS-PrePost, which is freely distributed and runs without a license. Licensees of LS-DYNA automatically have access to all of the program's capabilities, from simple linear static mechanical analysis up to advanced thermal and flow solving methods.
Furthermore, they have full use of LS-OPT, a standalone design optimization and probabilistic analysis package with an interface to LS-DYNA.
