CONTROL OF VIBRATIONAL POWER INPUT TO SEMI-INFINITE ANISOTROPIC BEAM
Keywords:
KeywordsAbstract
The time averaged vibration power input to semi-infinite beam of
anisotropic materials subj ected to simultaneously acting bending
f orce and moment excitations is presented. Fibre-reinforced
composite materials of seve ral types ofply and ofvarious laminate
arrangement were selected. The power input was minimized due to
cancellation effect attributed to the coupling mobility between
f orce and moment components. The cancellation effe ct f requency
could be controlled by regulating the properties ofthe anisotropic
materials.
