International audienceIn a typical pin-loaded joint used to assemble glass plates, the hole in a glass plate is reinforced by a steel ring glued to the glass plate via a soft resin layer. Thus, the ring is in direct contact with the steel bolt and prevents the glass plate from high stress concentration. This paper proposes an analytical approach to solving the resulting conforming contact problem. The strain and stress fields inside the resin layer are first determined by exploiting the fact that the stiffness of the material constituting it is much smaller than the stiffness of steel and glass. After finding the relevant Green functions for the ring and pin, the frictionless contact between them is then formulated in terms of an integral equation with a Fourier series as the kernel. This integral equation is solved by neglecting the terms of high orders and transforming it into the Cauchy singular integral equation. The derived analytical results for the contact pressure and angle are finally compared to and validated by those obtained by the finite element method. (C) 2006 Elsevier Ltd. All rights reserved
Pin-loaded joints are frequently used to assemble tempered glass plates. To prevent such structures from fracture, a holed glass plate is reinforced by a steel ring and glued to it through a soft resin layer. The present work first models and identifies the mechanical behaviour of the constituent materials and then analyzes the failure process of tempered glass structures with pin-loaded joints, in which unilateral contact, friction, damage and residual stresses are involved. The numerical results obtained by the finite element method are in good agreement with the experimental ones issuing from the real size test.
