Temperature Effect on Stress-Strain State of Supported Flexible Plate With Initial Deflection
Abstract
The article presents the analysis of the temperature effect on the stress-strain state of the supported flexible plate with initial deflection with regard for physical and geometrical nonlinearities. The temperature varies by the linear law in the longitudinal direction. The tested metal plate (St3) consists of two panels partitioned by a support of а ´ b size and h thickness. The results of numerical calculations are presented and the obtained dependences of deflections and deformations on the temperature effect and initial deflection are analyzed. It is shown that modifications of mechanical properties of the material depend on temperature changes.
