Blast Modeling with LS-DYNA®


  • You should be fa­mil­iar with LS-DY­NA.
  • We strong­ly rec­om­mend tak­ing the class "Meth­ods & Mod­el­ing Tech­niques: Pre­req­ui­sites for Blast & Pen­e­tra­tion Sim­u­la­tion."


LS-DY­NA is well suit­ed for sim­u­lat­ing blast events. LS-DY­NA, for in­stance, can solve air blast prob­lems, the tra­di­tion­al fo­cus of blast mod­el­ing, as well as help de­sign troop trans­porta­tion by mod­el­ing buried ex­plo­sive charges. With LS-DY­NA, you can sim­u­late these events us­ing any com­bi­na­tion of La­grange, Euler­ian (MM-ALE) and sim­ple en­gi­neer­ing solvers.

This class fo­cus­es on the ap­pli­ca­tion of LS-DY­NA for the sim­u­la­tion of blast load­ing. We will il­lus­trate the analy­sis meth­ods through case stud­ies. We will al­so em­pha­size mod­el­ing tech­niques:

  • guide­lines for which tech­nique(s) to se­lect,
  • in­sights in­to which tech­niques work well and when,
  • and pos­si­ble pit­falls in mod­el­ing choice se­lec­tions.

We will present enough math­e­mat­i­cal the­o­ry for each tech­nique to pro­vide you with ad­e­quate knowl­edge to ap­pro­pri­ate­ly ap­ply them. How­ev­er, this train­ing class is not a sub­sti­tute for the in-depth treat­ments pre­sent­ed in the as­so­ci­at­ed LS-DY­NA train­ing class­es, mean­ing Ad­vanced ALE and ALE/­Euler­ian Flu­id Struc­ture In­ter­ac­tion.
