Bu çalışmada, tabakalı bir yarım uzayın tepkisinin sayısal olarak belirlenmesi için sınır eleman yöntemi kullanılmıştır. Zeminin malzeme davranışının lineer elastik olduğu varsayılmıştır. Sınır eleman yöntemi, Fourier dönüşüm uzayında kullanıldı. Bu makalenin odak noktası, tabakalı bir yarım uzayın iç noktalarında oluşan gerilme ve deplasman dağılımlarının belirlenmesisdir. Bu amaca ulaşmak için bu çalışmada, üç boyutlu elastik veya visko-elastik problemler için bir bilgisayar programı geliştirilmiştir. Sınır eleman formülasyonu kullanılarak belirlenen tabakalı bir yarım uzaydaki gerilme ve deplasman dağılımları şekillerde sunulmuştur.

Determination of Tire Contact Stress and Deflection Distributions in a Layered Half-Space Using 3-D Boundary Element Method

In this study, the Boundary Element Method (BEM) was employed for the numerical determination of the response of a layered half-space. The material behaviour of the soil was assumed to be isotropic and linear elastic. The BEM was used in the Fourier transform space (FTS). The focus of this paper is to determine the stress and deflection distributions of interior points of a layered half-space. To achieve this aim, in this study, a computer program is developed for three-dimensional elastic or visco-elastic problems. The results of stress and deflection distributions in a layered half-space determined using boundary element formulation are presented in figures.
