Influence of the Connectedness of Thermoelastic Fields on the Stress-Strain State of a Circular Rigidly Fixed Plate
In the case of heating the upper and lower surfaces of a circular rigidly fixed plate, a new closed solution to the dynamic problem of thermoelasticity is constructed. To obtain the calculated ratio, the method of finite biorthogonal transformation is used, which is used for arbitrary external temperature effects in time (the boundary condition for thermal conductivity of the first kind). The software was developed to analyze the effect of thermoelastic fields on the temperature field and the stress-strain state of the structure. Numerical analysis of the calculation results shows that for a given external temperature effect, the rigidity (physical and mechanical properties and geometric dimensions) of the elastic system has a significant effect on its thermoelastic field. At the same time, taking into account the rate of change in the volume of the plate, the temperature and mechanical stress during the heating of the plate decrease. In the future, under constant temperature conditions, field coupling will not be observed.
The calculated ratios obtained make it possible to determine the stress-strain state of a rigidly fixed circular plate under an arbitrary axisymmetric temperature external action.
