This paper presents an investigation on the nonlinear dynamic response of piezoelectric plate reinforced with boron nitride nanotubes (BNNTs) under combined electrothermo-mechanicai loadings.By employing nonlinear strains base on plate theory and utilizing piezoelectric theory including thermal effects, the constitutive relations of the piezoelectric plate reinforced with BNNTs are established.Then the dynamic goveming equations of the structure are derived through variational principle.Using the difference method in space and Newton-Newmark method in time, the whole problem is resolved by the iteration method.In numerical examples, the effects of voltage, temperature, mechanical load, volume fraction, as well as external excitation frequency on the nonlinear dynamic response of piezoelectric plate reinforced with BNNTs are discussed in detail.

我认为目前盆景界不少同志称之为“树桩盆景”的提法,很不恰切,特别是简称桩景或古桩更不妥。桩是树木的残余,从山野中挖来的树桩制作成盆景,当然可以称为树桩盆景,但不能概
