Abstract
The purpose of this study is to clarify thermally induced vibration of a thin‐walled rectangular plate with inhomogeneous material properties in a thickness direction due to cyclic variation of thermal and mechanical loads. An effect of inhomogeneity of material properties on thermoelastic responses due to thermal and mechanical loadings is examined. When frequencies in loadings are close to natural frequency of the plate, vibrations due to both loadings offset each other. It is found that an effect of variation of natural frequency due to inhomogeneities in Young's modulus or mass density on dynamic response is more significant than that of variation of thermal resultant moment due to inhomogeneity in coefficient of linear thermal expansion.
