MODAL VIBRATION
A modal vibration helps to determine the vibration characteristics of a mechanical structure or component, showing the movement of different parts of the structure under dynamic loading conditions. The natural frequencies and mode shapes are important parameters in the design of a structure for dynamic loading conditions.

MODAL RESPONSE
A modal response is how structures respond to varying types of vibration.

DYNAMIC RESPONSE
Dynamic response is a type of structural analysis which covers the behavior of a structure subjected to dynamic loading. Dynamic loads include hydraulic shock, wind, snow, earthquakes, and blasts. This additional pressure puts stress on the piping material and its joints.
