Stress reduction of plate under external load by its cover layer with initial stresses

В роботі розглянуто спосіб впливу на розподіл напружень навантаженої плити, що лежить на жорсткій основі, за допомогою зовнішнього попередньо напруженого шару. Проведено аналіз отриманих результатів. Визначено доцільність покриття матеріалів зовнішнім шаром із початковими напруженнями для зменшення у них напружень.We consider a way of influence on the distribution of loaded plate stress lying on a rigid base, with external prestressed layer. Axisymmetric task was posed. We examined conditions under which it is correct to use correlation of linearized elasticity theory for bodies with initial stresses. By Hankel’s integral transformation it was received solution obtained through functional equations system. The functional systems Numerical solution was implemented by Gauss method. We received the conclusion about plate stress decrease if initial layer stresses are сompressible. The analysis of the results was carrying out. Feasibility of materials coating by external layer with initial stresses for reducing their stress was determined
