Динамічні процеси в тонкому циліндрі при тепловому опроміненні торця
Я.О. Жук, І.К. Сенченков, О.В. Бойчук
Abstract
The processes of generation and propagation of a stress pulse
and temperature variations caused by a thermal impact at the
face of a long thin steel cylinder are investigated. The
statement of the dynamic coupled problem of thermomechanics is
used along with the thermodynamically consistent theory
of the inelastic behavior of a material. It is solved
numerically by the finite element method. Main properties of
a thermomechanical state in the vicinity of the irradiated
end and the stress pulse propagation accompanied with the temperature
variation are studied. Relations between the parameters of a
thermal pulse and a stress wave are established.
