ESTIMATION OF LOAD CAPACITY OF ADHESIVE JOINTS FOR TRANSPORT ENGINEERING
Adhesive joints are widely applied in transport engineering. Crack resistance is an important parameter determining the load capacity and durability of adhesive joints. The calculation-experimental method, which allows to raise the accuracy and reliability of an estimation of the crack resistance of the adhesive compositions is proposed. The proposed method can be implemented using a test station that ensures the loading of double cantilever glued beams by equal and oppositely directed moments. The mathematical model for determining the value of crack advancing energy, includes only one independent parameter (the bending moment) was obtained. It is established that change of geometrical parameters of the proposed experimental models slightly effects (less than 3.5 %) on value of crack advancing energy.
