•Direction 1 is toward from local node 1 to node 2.
•Direction 2 is vertical direction of Direction 1.
•G11 to G33 represents the component of constitutive matrix in shell material.
•Damping Ratio (
): Defines the
damping ratio. The structural damping ratio of element and the damping matrix of
is C computed from the following equation.
where:
: Damping Matrix
: Stiffness Matrix
: Damping Ratio
•Stress-strain matrix (E)
