Method development

In order to perform reliable, nonlinear dynamic calculation, you need experience in dealing with the software. We are here for you with all our support and advise. Together we can work out how you can use LS-DYNA for your specific needs.

Since many years DYNAmore collaborates in code development of the LS-DYNA with LSTC. Many constitutive models, e.g. for composite materials, light alloys or elastomers, were already developed and implemented by colleagues of DYNAmore in the 1990s. At present a code development group, seamlessly integrated into the release management of LSTC, is working at the DYNAmore offices in Germany, Sweden and France to implement new features and methods in LS-DYNA, LS-OPT and LS-PrePost for clients from all over the world. Our capabilities and skills cover the entire spectrum of finite element technology including especially constitutive models, isogeometric analysis and thermal coupling. However, parallelization and porting of the code to various hardware platforms or operating systems is typically done at LSTC.

Examples of past projects include but are not limited to:

  • Development of spot weld and other connection models
  • Development of damage and fracture models, i.e. GISSMO has been developed at DYNAmore
  • Development of various constitutive models to describe fracture of laminated glass, unreinforced, short fiber and endless fiber reinforced polymers
  • Development of mapping algorithms to enable seamless computation of the component manufacturing
  • Development of methods for realistic simulation of air-bag unfolding/expansion, including effects due to fluid-structure interaction of gas and surrounding vehicle or dummy parts
  • Procedures for the simulation of airbag folding processes
  • Development of modelling techniques for the assessment of whiplash injuries during vehicle rear impact
  • Method development of active hood systems for pedestrian protection
  • Code development to support the impact simulation of vehicle structures with fork lifts, other cars and trucks, road side structures, as well as support the assessment of seat development for minimization of whiplash injury and head impact in vehicles to rate occupant safety
  • Code and method development of splashing in vehicle tanks
  • Modelling of the multi-physic characteristics of the hot stamping process including complex constitutive behavior
  • Development of advanced identification and calibration methods for constitutive models involving the inclusion of new hardware test methods
  • Investigations to assess the numerical stability of large scale simulations on thousands of computing cores
