Explicit Dynamic Analysis | Car Bumper | Basics of (ME) Tutorial 31

“Explicit” refer to type of time integration methods used to perform dynamic simulations. Explicit time integration is more accurate and efficient for simulations involving – Shock wave propagation – Large deformations and strains – Non-linear material behaviour – Complex contact – Fragmentation – Non-linear buckling. Typical applications are drop tests and impact and penetration. ANSYS Explicit Dynamics analysis software provides simulation technology to help simulate structural performance long before manufacture.

ANSYS explicit dynamics analysis software solutions are capable of solving short-duration, large-strain, large-deformation, fracture, complete material failure, and structural problems with complex contact interactions.A time integration method used in Explicit Dynamics analysis system. It is so named because the method calculates the response at the current time using explicit information Once the body is meshed properly, the next step is to define initial conditions or boundary conditions. At least one initial condition is required to complete the setup.

After defining the initial conditions (initial velocity, Angular velocity), the analysis setting has to be maintained as per the problem requirement. In the analysis setting, time steps have to be defined explicitly. The solution time depends on the time steps.
