WebModal analysis is the procedure for solving the simulta-neous system of ODEs. The system is transformed into a set of independent ODEs of which its solution is readily determined. The actual solution are formed by combining the basis together; transform the solution back to the original system. 4.3 Modal Analysis Ch. 4: Vibration of Multi-DOF ... WebThis paper studies the in-plane free vibration of axially functionally graded (AFG) circular arches with non-uniform cross-section. The geometric and material properties of circular arches with regular polygon cross-section vary symmetrically about the mid-arc along the axial direction in quadratic polynomial form. The governing differential equations of the …
