Material Modeling and User Defined Materials in LS-DYNA

LS-DYNA is a leading finite element program in large deformation mechanics, vehicle collision simulations and crashworthiness design as well as for metal forming simulations. The vast variety of application areas means that there are a great number of material models available in LS-DYNA, currently more than 250 models.

In this seminar we will give you the theoretical background of a number of material models in LS-DYNA and point at their differences. In addition, the seminar serves as an excellent introduction to the LS-DYNA user defined material interface. The seminar includes a number of computer exercises.

 

Prior knowledge:

The seminar is suited for users who have used LS-DYNA to
some extent and want a more in depth understanding and categorization of its
material models or want to develop their own material models or failure criteria.

 

Seminar outline:

  • Continuum mechanics: motion, deformation, stresses, strains, objectivity
  • Thermodynamics: its consequences for material modelling
  • Elasticity and visco-elasticity: hypo- and hyperelasticity, Kelvin and
    Maxwell models
  • Rubbers: the Mooney-Rivlin and Ogden models
  • Biomechanical materials: (on request only)
  • Metal plasticity and visco-plasticity: isotropic and kinematic hardening, isostropic and anisotropic yield criteria, Cowper and Symonds rate model
  • Polymers: modeling concepts for polymer plasticity
  • Foams and composite materials: low density and crushable foams,
    laminates
  • Concrete, rock and soil: Granular material model features
  • Damage, failure and temperature dependence: ductile and brittle failure, GISSMO and DIEM
  • User defined material models in LS-DYNA: a thorough treatment
