본문내용
Mass Matrix
M=m[■(1.5&0&0@0&1.5&0@0&0&1)]
Stiffness Matrix
Influence Coefficients Method: Each column of the stiffness matrix, e.g. column j, corresponds to DOF j. To obtain values of each column, a unit displacement is imposed at DOF j and zero at the others. The stiffness influence coefficients are Kij.
