| This paper is concerned with the effect of axial forces on buckling control of beams with adhesively bonded piezoelectric layers. The type of the system support makes it possible to apply it in compliant mechanisms for precision engineering. In the work, the influence of piezoelectric actuation on buckling behavior of non-uniform Euler-Bernoulli beams with ends restrained against longitudinal displacements is analyzed in detail. It is shown that the in-plane stretching or compressing being a result of the piezoelectric residual stresses may, dependently on the sign of the applied voltage, either counteract or evoke the buckling of the structure. A change in the buckling mode shape for the first critical buckling load with increasing stiffness of elastic foundation is observed. |
