Dynamic analysis involves any class of problems with time varying loads and effects. For example, a building experiencing seismic ground shaking would require this type of analysis to determine the variation of structural forces with time. A crashworthiness test of a vehicle against a wall is a dynamic event because large impulsive forces are imparted over a short period of time. From an FEA perspective, dynamic analyses take a large amount of time due to extreme non-linearities present. At ENA2, our engineers not only have the experience to prepare accurate dynamic models, but we have the knowledge of applying best practices to run dynamic analyses as efficiently as possible.
