METHOD OF ESTIMATION OF STRENGTH AT SHEAR ADJUSTMENT OF CERAMIC PROTECTION Russian patent published in 2017 - IPC G01M5/00 G01N3/24 

FIELD: testing equipment.

SUBSTANCE: determination value of breaking strength under static loading adhesive compound such as "pipe in pipe" sample compressive force causes a shift of the inner tube relative to the outer tube in the direction of axis of the sample. Size adhesive model sample compound and a compressive force, whereby the adhesive layer having the shear strain, selected in view of matching the stress state of the adhesive layer in the adhesive joint of the ceramic radome and stress state of the model sample of the adhesive connection using finite element models. The ratio between the equivalent stresses in the adhesive layer of the adhesive bonding of the ceramic radome, the geometric parameters of the model sample of the adhesive layer and the force to shear a sample model inner tube, is defined by the formula.

EFFECT: increased efficiency of monitoring the bonding strength of ceramic radomes in the production process and during the development work by replacing full-scale testing of their product models that reproduce the conditions of the adhesive bond.
