Mathematical modeling and analysis of thermostressed state of bimetallic plate under electromagnetic action in the mode with pulse modulated signal

Musij R., Melnyk N., Dmytruk V.

865--870

The thermostressed state of a bimetallic plate under the electromagnetic action in the mode with pulse modulated signal (MPMS) at the resonant frequencies of the electromagnetic field is studied. There are established the critical values of the parameters of the electromagnetic action at which the bimetallic plate loses its load-carrying ability as a constituent element.

The mathematical modeling and investigation of the stress-strain state of the three-layer thermosensitive hollow cylinder

Rakocha I., Popovych V.

Acta Mechanica et Automatica

2016

Vol. 10, no. 3

181--188

Stationary temperature distribution in a three-layer infinite hollow cylinder based on the thermosensitive body model was determined. The cylinder is subjected to the steady temperature on the inner surface and on the outer one is present the convective heat exchange. In the second layer exist heat sources with parabolic dependence on radial coordinate. The components of the thermostressed state have been found. The influence of the temperature dependence of the thermal and mechanical components characteristics of materials on the temperature distribution has been investigated.
