Abstract
Solution of nonlinear non-stationary task of calculation is offered distributing of the temperature field is in the volume of cylinder standard by the finite element method on the example of reaction of epoxy resin ED-20 with polуethylenpolyamines. Calculation researches of dependence are executed temperatures from time in the extreme points of standards in system cylinder form. Calculation information is confronted with experimental measuring.
