Изобретение относитс  к механике , в частности к образцам дл  оценки прочности адгезионных соединений при сдвиге.The invention relates to mechanics, in particular to samples for assessing the strength of adhesive joints under shear.

Цель изобретени  - повышение точности определени  прочности адгезионного соединени  путем исключени  внецентренного раст жени  пластин на кра х нахлестки.The purpose of the invention is to improve the accuracy of determining the strength of the adhesive joint by eliminating the eccentric stretching of the plates at the edges of the overlap.

На чертеже представлен образец дл  определени  прочности адгезионного соединени  при сдвиге.The drawing shows a sample for determining the strength of an adhesive compound in shear.

Образец дл  определени  прочности адгезионного соединени  содержит две одинаковые подложки 1 и 2 в виде пластин толщиной о, соединенных между собой клеевым слоем 3 внахлестку . Кажда  из пластин выполнена из двух плоских участков. Их свободные участки расположены в одной плоскости и предназначены дл  приложени  раст гивающей нагрузки. Склеенные внахлестку участки образуют с плоскостью свободных участков тупой угол 06 , величина которого составл етThe sample for determining the strength of the adhesive joint contains two identical substrates 1 and 2 in the form of wafer plates of thickness o interconnected by an adhesive layer 3 overlap. Each of the plates is made of two flat sections. Their free areas are located in the same plane and are intended for application of a tensile load. The overlapped areas form an obtuse angle 06 with the plane of the free areas, the value of which is
