Technical scheme of the present invention is: produce even drawing stress or shear stress by a simple unidirectional compressive load on the cross bonding sample bonding plane of two kinds or solid material of the same race, the stress during by cracking is determined interface tension strength or shear resistance;
The pulling strengrth at described interface test concrete operations can be 1) specimen preparation: two kinds of bonding materials of needs are cut into the square section stub earlier, adopt the bonding cross sample of making of right-angled intersection; 2) with a horizontal suspension in the bonding sample in metal anchor clamps, another root sample is across the anchor clamps both sides, it is held by the anchor clamps both sides, force in the sample of horizontal suspension in clip groove, adopt the common material experimental machine to carry out compression experiment, make the interface produce drawing stress, can record the stretching bonding strength; The shear resistance at described interface test concrete operations can be 1) specimen preparation: two kinds of bonding materials of needs are cut into the square section stub earlier, adopt the bonding cross sample of making of right-angled intersection; 2) with in one in the sample of the bonding back clip groove that vertically the insertion metal makes, another root horizontal bar is then held by one side of anchor clamps, force on the sample of perpendicular insertion anchor clamps, allow its pressurized make its bonding interface produce shear stress, thereby can test the shear resistance when ftractureing.
The invention has the beneficial effects as follows:
1. the invention solves the problem of the stretching bonding strength that can't record hard brittle material over.
2. the present invention obtains stretch bonding strength and shear bond strength simultaneously with simple method, need not change specimen shape and anchor clamps.
3. the preparation of specimen holder of the present invention is simple, workable.
4. the present invention both can test the bonding strength of metal and metal, also can test pottery and metal, pottery and ceramic bonding strength.Intensity is calculated simple and clear, need not set up mechanical model and numerous hypothesis prerequisites.
