Methods for Airblast on Structures (Blast Modeling)

Blast events form a class of simulation environments well suited to the solution capabilities of
LS-DYNA. LS-DYNA is unique in offering the analyst the choice of Lagrange, Eulerian (ALE) and Simple
Engineering solvers, and combinations of these solvers, for simulating high energy events such as
blast loading. In addition to air blast, the traditional focus of blast modeling, buried explosive charges
have recently become important in the design of troop transportation.


This class focuses on the application of LS-DYNA for the simulation of high energy events. The analysis
methods, and modeling, are illustrated through case studies. An emphasis is placed on modeling
techniques: guidelines for which technique(s) to select, insights into which techniques work well
and when, and possible pitfalls in modeling choice selections.


Sufficient mathematical theory is presented for each technique to provide the typical user with
adequate knowledge to confidently apply the appropriate analysis technique. However, this training
class is not a substitute for the in-depth treatments presented in the associated LS-DYNA training class,
i.e. „ALE/Eulerian & Fluid Structure Interaction.”
