Vibration of FG sandwich beams under moving load using first-order shear deformable beam element
The dynamic response of functionally graded (FG) sandwich beams excited by a moving point load is studied by the finite element method. Based on the first-order shear deformation beam theory, a finite beam element is formulated by using the hierachical shape functions. The beam is assumed to be form...
