Shock Analysis with USA/LS-DYNA®


  • At­ten­dees must be di­rect­ly em­ployed by a cur­rent USA li­censed en­ti­ty, typ­i­cal­ly a gov­ern­ment agency or cor­po­ra­tion.
  • In­ter­na­tion­al at­ten­dees must pre­reg­is­ter for the class through a pur­chase or­der of the USA li­censed en­ti­ty. That pur­chase or­der must iden­ti­fy the at­tendee by name, de­part­ment, su­per­vi­sor, and pass­port num­ber. The at­tendee must present the pass­port when at­tend­ing.
  • Pri­or LS-DY­NA ex­pe­ri­ence is rec­om­mend­ed be­cause there are ex­er­cis­es through­out the class.
