Forecasting the Strength of an Adhesive Bond Over a Long Period of Time

Abstract

We consider the problem of the adhesion compound of calculation by finite element method in axisymmetric along two axes: the axial z and radial r. To improve the accuracy of the solution to the problem posed, a number of optimizations are introduced: obtaining an exact solution of the stiffness matrix and the load vector for a given interpolation polynomial, using a nonconstant approximating time interval, thickening of the finite element grid to the edges of a cylindrical body, etc. At the end, predicting the strength of the adhesive compound in question. At the end, an analysis of the result obtained and a prediction of the strength of the adhesive compound under consideration are given.
