Failure, Fracture, & Damage

Prerequisites

  • Equiv­a­lent knowl­edge to an in­tro­duc­to­ry class in LS-DY­NA® is rec­om­mend­ed.

Syllabus

This course teach­es you how to mod­el frac­ture, dam­age, and fail­ure in LS-DY­NA. The dif­fer­ent method­olo­gies to mod­el fail­ure and frac­ture in LS-DY­NA will be pre­sent­ed and dis­cussed. All for­mu­la­tions in LS-DY­NA, in­clud­ing La­grangian, Euler­ian, SPH, XFEM, EFG, and DEM, will be dis­cussed. This course in­cludes sev­er­al ex­am­ples, de­signed to il­lus­trate and re­in­force the con­cepts pre­sent­ed.
