We study piezoelectric semiconductor fibers under axially‐compressive loads. The fibers have some initial geometric imperfections, modeled as initial deflections in the paper, and undergo coupled axial compression and bending. A one‐dimensional nonlinear model is derived from the three‐dimensional phenomenological theory of piezoelectric semiconductors. A theoretical analysis is performed and an analytical solution is obtained for a simply‐supported fiber. Numerical results are presented, showing the effects of the geometric imperfection on coupled bending and compression as well as charge distribution.

不完美的压电半导体纤维的压缩和弯曲耦合
我们研究轴向压缩载荷下的压电半导体纤维。纤维具有一些初始几何缺陷，建模为纸中的初始挠度，并经受轴向压缩和弯曲耦合。一维非线性模型是从压电半导体的三维现象学理论得出的。进行了理论分析，并获得了简单支撑纤维的分析解决方案。给出了数值结果，显示了几何缺陷对耦合弯曲和压缩以及电荷分布的影响。
