研究目的
To analyze the dynamic behaviors of a multilayered two-dimensional piezoelectric quasicrystal circular cylinder filled with compressible fluid, considering imperfect bonding between layers and various loading conditions.
研究成果
The state-space approach effectively analyzes the dynamic behaviors of multilayered PQC cylindrical shells. Natural frequencies decrease with increasing length-to-radius and radius-to-thickness ratios. The critical load and pre-buckling behavior are accurately predicted, and dynamic responses under impulse loads are influenced by fluid density and interfacial imperfections.
研究不足
The study assumes simple support at both ends and imperfect bonding between layers. The influence of interfacial imperfections and fluid density on dynamic responses is considered, but other factors like temperature effects are not included.
1：Experimental Design and Method Selection:
The state-space approach is employed to derive the dynamic behaviors of the cylindrical shell. The method involves solving state equations based on three fundamental equations using the integration method.
