Advanced Engineering Simulations with LS-DYNA

Advanced Engineering Simulations with LS-DYNA


Today’s engineering challenges are too complex to be solved by traditional methods alone. In industries such as automotive, defense, rail systems, energy, and manufacturing, performing durability, safety, and performance tests in a virtual environment not only reduces costs but also accelerates R&D processes. At this point, LS-DYNA stands out as one of the most advanced finite element software solutions, offering powerful solvers and multiphysics capabilities that have become indispensable for engineers worldwide.

LS-DYNA’s Simulation Capabilities

1. Crash and Impact Analysis

One of the most common applications of LS-DYNA is crash simulations in the automotive industry.

Vehicle crash tests (NCAP, FMVSS, Euro NCAP)

Pedestrian protection scenarios

Drop tests for phones, electronics, and appliances

Defense industry ballistic and impact simulations

Thanks to its explicit solver, LS-DYNA can simulate high-energy events that occur within milliseconds with exceptional accuracy.

2. Metal Forming Analysis

Sheet metal forming is a critical process in automotive and white goods industries. LS-DYNA provides:

Drawing, bending, hydroforming, tube expansion

Drawbead and blankholder definitions

Formability analysis (FLD), thinning and tearing predictions

Springback (elastic recovery) simulations

These capabilities allow engineers to optimize die design, material selection, and production processes.

3. Blast and Ballistic Analysis

In the defense sector, blast and ballistic analysis plays a key role.

CONWEP and LOAD_BLAST_ENHANCED for TNT equivalence

ALE (Arbitrary Lagrangian-Eulerian) for air and shock wave modeling

Armor and composite penetration/failure simulations

Explosion load effects on structures and vehicles

This makes it possible to predict the resistance of military vehicles and protective structures before physical testing.

4. Fluid-Structure Interaction (FSI)

LS-DYNA is not limited to structural analyses; it also models fluid-structure interactions with high precision.

SPH (Smoothed Particle Hydrodynamics) for free surfaces and sloshing

ICFD/ALE methods for tanks, pipelines, and ship structures

Underwater explosion (UNDEX) analysis

Through FSI, engineers can evaluate liquid effects in pipelines, fuel tanks, or naval structures reliably.

5. Thermal and Thermomechanical Analysis

Beyond mechanics, thermal behavior is also critical in product performance. LS-DYNA supports:

Welding, laser cutting, and heat treatment simulations

Friction-induced heating

Temperature effects in forming processes

Thermal degradation of composites

These allow engineers to analyze temperature-dependent material behavior accurately.

6. Composite and Lightweight Material Analysis

Lightweight design has become vital in automotive and aerospace industries. LS-DYNA offers:

Lamina-based composite modeling

Delamination prediction

Fabric and woven material simulations

GISSMO and Hashin failure criteria

This enables advanced simulation of damage and failure in composite structures.

7. Vibration and NVH Analysis

In addition to explicit solvers, LS-DYNA’s implicit capabilities provide:

Natural frequency (modal analysis)

Harmonic response analysis

Noise, vibration, and harshness (NVH)

Fatigue analysis under cyclic loads

These simulations are essential in automotive, rail, and industrial machinery to ensure comfort and durability.
