FAQS 4
What is a four point bending test?
The four point bending test described in EN1288-3 (Fig. 1) consists of a 1100 mm by 360 mm glass plate that is held by two support rollers spaced 1000 mm apart. Two bending rollers spaced 200 mm apart press on the glass from the other side. Between the rollers and the glass, a layer of rubber is used for protection.
Does flat glass have tensile bending strength?
Proposed evaluation procedure of the tensile bending strength of flat glass. 8. Conclusions Symmetrical 4PB tests were conducted in this study to investigate the tensile bending strength and fracture behavior of ultra-white annealed and fully tempered glass specimens.
What is the tensile bending strength of annealed glass?
For the ultra-white annealed and fully tempered glass specimens, tensile bending strengths determined by the standard method in EN 1288-3 and the modified method are roughly comparable, with all differences being less than 5%, as presented in Table 3.
Do glass bending test results differ from actual bending tests?
The present paper will show that for tests with high deformation, which becomes more relevant for smaller glass thickness and chemically strengthened glass, these results differ vastly from the actual behaviour of the glass in the four point bending test as it is performed in most industry and lab settings.
