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:
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
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
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:
Explicit-Implicit switching for studying steady state deformation
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:
These features make LS-DYNA an ideal tool for engineers practising performance-based earthquake engineering.
LS-DYNA has the capabilities to simulate a wide range of different
physical phenomena using analysis techniques such as:
Explicit and Implicit Time Integration Schemes
Sophisticated Material Models
Complex Contact Conditions
Thermal Analysis and Thermal Structural Coupling
Fluid Dynamics and Fluid Structure Interactions
Smooth Particle Hydrodynamics (SPH)
Element Free Galerkin (EFG)
LS-DYNA has over 130 material model which can be used to simulate
a wide range of engineering materials from steels to composites to
soft foams to concrete.
LS-DYNA has an extensive element library including 1d discrete, beam,
shell and solid elements. For which a range of both under integrated
and fully integrated element formulations.
The fully automated contact analysis capabilities in LS-DYNA are easy
to use, robust and validated. They use both constraint and penalty
based methods to satisfy contact conditions. These techniques have
worked extremely well over the past 20 years in numerous applications
such as crashworthiness, drop testing and occupant safety. Multiple
types of contact definitions and friction models are available.
