Prediction of Strength for Inhomogeneous: Defective Glass Elements Based on the Sequential Partitioning of the Data and Weibull Statistical Distribution

An analytical approach based on the on the sequential partitioning of the data and Weibull Statistical Distribution for inhomogeneous - defective materials is proposed. It allows assessing the guaranteed strength of glass structures for the low probability of fracture with a higher degree of reliability. Parameters of equations for the piecewise...

Structural Strength of Laminated Glass

The subject area "structural strength of materials" is defined generally as а complex of strength characteristics of materials and structural elements, obtained under special mechanical tests. It is shown that these tests should take into account not only the physical and mechanical properties of the material, but technology, blank processing,...

Structural Strength of Heat-Strengthened Glass

The paper considers the determining factors in the structural strength of heat-strengthened glass. The values of residual stress were obtained experimentally at different points on the surface of specimens of heat-strengthened, HS-glass and fully tempered, FT-glass using a SCALP-4 laser scanning polarimeter. The distribution of residual stresses...

Improving the engineering strength of heat strengthened glass

Although glass is increasingly used as a structural material, glass is not produced to strength standards, like steel and concrete. Of the three types of glass: annealed, heat strengthened and fully tempered, only heat strengthened glass has the properties to function as a safe structural material. These properties are strength, resistance to...

The structural strength of glass: Hidden damage

We discuss “hidden damage” of glass by the rolling process, which results in heterogeneous distribution of microcracks on the edge surface of glass element, which are the fracture source deteriorating glass element strength. It is shown that removal of this damage on the edges of glass elements increases the engineering strength of float glass...

The strength of glass, hidden damage

The strength of float glass is a necessary engineering parameter. Determining this strength is a complex problem. Earlier results have shown that statistically bending test results are not a homogeneous group. To explain this, a theoiy of "hidden damage" is proposed. The essence of this theory is that the different sides of float glass are...

Corrosion effects on soda lime glass

Although soda lime glass is the most common used transparent material in architecture, little is known about the corrosion effects on long term strength and the interaction between corrosion and defects. Extensive testing on soda lime bars under different environmental conditions and different degrees of damage has resulted in a inore clear...
