Modal Analysis Equation Calculator

Modal analysis equation describes the dynamics of a structure under loads.The formula is given by:

Where:

• $M$ is the mass matrix,
• $C$ is the damping matrix,
• $K$ is the stiffness matrix,
• $q$ is the vector of modal displacements,
• ¨q¨​ is the vector of modal accelerations,
• ˙q˙​ is the vector of modal velocities, and
• $F$ is the vector of modal forces.
