Drop Test or Impact Analysis

Drop Testing or Impact Testing is the simulation analysis of a product impacting with a surface. This is critical in manufacturing design from tools to modeling natural phenomena, such as Mathematical Modeling of Asteroid Falling into the Ocean  (pdf paper opens to  new window)

Concerns in manufacturing:

Design these products wherein certain components act as energy absorbers on impact, thereby protecting vital components.

The damaged components manufactured as energy absorbers can then be repaired or replaced

Analysis simulation is to produce a model capable of predicting stresses and strains on the components thereby saving production time and expense..

LS-DYNA's flexibility to provide user-definition of key parameters is a major factor in simulating drop/impact analysis. This flexibility offers engineers the capability to develop products with reliability performance.
