Conclusions
-
1.
Testing based on plane bearings does not give a full representation of the strength of commercial glass under monoaxial compression.
-
2.
The proposed method of testing compound glass testpieces, based on increasing the load bearing capacity of the ends of smooth rods under compression, provided a means of establishing that the commercial glass adopted by industry has a compressive strength of up to 200–250kgf/mm2 with a small scatter of the data relating to properties.
-
3.
Mechanical surface damage of commercial glass leads to a considerable reduction of its compressive strength.
