Crashworthiness in LS-DYNA®


  • Six months to two years ex­pe­ri­ence us­ing LS-DY­NA


This class is de­signed for en­gi­neers and sci­en­tists who are look­ing to ef­fec­tive­ly use LS-DY­NA for au­to­mo­tive crash­wor­thi­ness, in­dus­tri­al drop test­ing, or oth­er low ve­loc­i­ty im­pact ap­pli­ca­tions. The class starts with a short in­tro­duc­tion to LS-DY­NA’s ap­pli­ca­tion in the field of crash­wor­thi­ness en­gi­neer­ing fol­lowed by var­i­ous top­ics that are es­sen­tial for every en­gi­neer. Top­ics cov­ered in this class in­clude mesh qual­i­ty, mesh con­ver­gence, shell el­e­ment tech­nol­o­gy, con­nec­tions such as spotwelds, con­tact, ma­te­ri­als, com­po­nent mod­el­ing, and best prac­tices.
