Structure response to external forces studied for dynamic behavior understanding.The formula is given by:
Where:
- is the mass matrix of the structure,
- is the damping matrix,
- is the stiffness matrix,
- is the vector of displacements of the structure at time ,
- ¨ is the acceleration vector of the structure at time ,
- Ë™ is the velocity vector of the structure at time ,
- is the vector of external forces or excitations applied to the structure at time .
