Contact interaction of the parabolic punch with preliminary stressed plate fixed on the rigid basis
Journal Title: Вісник Тернопільського національного технічного університету - Year 2016, Vol 82, Issue 2
Abstract
Solution of the contact problem on the interaction of the punch with preliminary stressed thick plate is presented in the article. Analytical solutions for the plate were found while it’s modeling by the preliminary stressed layer of the finale thickness. System of double and triple integral equations obtained here and solved while presenting the necessary functions as the finale set sums according to the Bessel functions with the unknown coefficients and further obtaining of the finale systems of linear algebraic equations for their finding. Basing on the obtained stress-strain state the effect of the punch configuration on the stressed state of the thick plate has been analyzed.
