Explicit Dynamics [new]
: It is widely used for drop tests of consumer electronics, automotive crashworthiness, metal forming processes, and terminal ballistics.
Because explicit solvers introduce artificial inertia to stabilize the small time step, you risk —where the model is so "heavy" in the simulation that it takes a different deformation path than reality. explicit dynamics
In structural mechanics, dynamic problems are governed by Newton’s Second Law: $$ M \ddotu + C \dotu + Ku = F(t) $$ Where: : It is widely used for drop tests
The most critical check for validity in Explicit Dynamics is the Energy Balance. metal forming processes
