Explicit Dynamics

Explicit dynamics is a time integration methodd used to perform dynamic simultions when speed is important. Explicit dynamics account for quickly chaning conditions or discontinuous events, such as free falls, high-speed impacts, and applied loads. Since these non-linear dynamics are integrated into the simulation, explicit dynamics is a preferred choice for simulating highly transient physical phenomena. [1]

Explicit dynamics tools help engineers to explore a wide range of challenges:

• Short-duration, complex or changing-body interactions (contact)

• Quasi-static loads (low strain rates)

• High-speed and hypervelocity impacts

• Severe loadings resulting in large material deformation

• Material failure

• Material fragmentation

• Penetration mechanics

• Space debris impact (hypervelocity)

• Sports equipment design

• Manufacturing processes with nonlinear plastic response

• Drop-test simulation

• Explosive loading

• Explosive forming

• Blast-structure interactions
