Abstract
A method has been developed that, with the availability of appropriate technical types of supplies, is an effective technology for conducting full-scale studies of structures exposed to temperature fields without the need to create temperature effects. Experimental effective test method, with the availability of appropriate technical types of supplies, for conducting full-scale studies of structures under the impact of temperature actions without the need to create temperature effects was developed. Its distinctive features are the simplicity of experimental part, the low cost of test itself, the physical clarity and logical foundation of results being obtained. The theoretical foundations of the method are based on the Betty-Maxwell energy reciprocity principle and consists in the replacement of a heated or cooled object with an unheated one. New experimental results shows that thermal displacement of the element (structure) in a predetermined direction and at a given time depends on the modulus of deformation of the 1st kind E, coefficient of transverse deformations ν, the thermal expansion coefficient α and the 1st invariant of deformation tensor defined in a predetermined number of points of the heated (cooled) element loaded by a single force. A program of experimental testing was suggested.
