Double glass component fragments

What is fragmentation pattern in glass plates?

Fragmentation pattern in glass plates having different size and a thickness of 5 mm, with σ CT = 55 MPa. Besides the analysis of the number of fragments per unit area, the distribution of the fragments mass is analyzed in terms of the inverse cumulative distribution function (CDF).

How to study fracture and fragmentation in tempered glass?

In the present paper, the problem of fracture and fragmentation in tempered glass is investigated by means of a numerical model. As computer power expanded in the last decades, different numerical methods have been proposed to study dynamic fragmentation. Two main categories exist for this purpose: particle and continuum methods.

How is fragmentation driven by eigenstresses in tempered glass plates simulated?

Fragmentation driven by eigenstresses in tempered glass plates is simulated with FEM. Cohesive method permits to model the complex crack pattern resulting from fragmentation. The model is validated against experimental results taken from the literature. The number of fragments increases by decreasing the plate thickness.

Does the tensile strength of glass affect fragmentation?

The data of Akeyoshi and Kanai regards plates of thickness 3 mm, 4.9 mm and 8.2 mm (see Fig. 2). The influence of the tensile strength of glass, σ c, on fragmentation was analyzed, since it is the mechanical parameter which presents the largest uncertainty, whereas elastic modulus and fracture toughness are easier to determine experimentally.
