Introduction to Explicit Dynamics using ANSYS LS-DYNA Software
This lecture presentation explores the basic concepts of explicit dynamics and the importance of simulation in dynamic problems. It starts with examples of dynamic simulations and explains the type of applications that Ansys LS-DYNA®, a nonlinear dynamics structural simulation software, would be best suited for compared to other Finite Element Analysis (FEA) tools Ansys provides. It also covers key topics related to explicit dynamic simulations like applications and characteristics of implicit vs. explicit methods, equations of motion and solution methods, energy summary, hourglassing, and mass scaling. Additional slides are included at the end, which briefly discuss material models and their specific requirements for running explicit dynamics simulations.
