Density of glass crack#
The important role of moisture is also discussed, as it is responsible for subcritical crack propagation, and thus lower durability of glass parts. Finally, we examine the practical strength of glasses, which is highly dependent on resistance to surface damage as well as to crack propagation (fracture toughness). We examine how plasticity occurs under sharp contact (e. g., indentation, scratch), until damage appears (cracks). This plastic deformation is highly dependent on glass composition it results from densification and shear flow, two mechanisms that are affected by the loading path, temperature and strain rate. But glasses can also deform plastically under high levels of compressive stress, particularly under sharp contact (indentation), because of high pressure and shear stress. We then discuss nonlinear elasticity in glasses, and how temperature and pressure impact on elastic moduli. We first review the most widely used methods for measuring the elastic moduli of glasses, and the state of the art regarding knowledge of the relationship between elastic moduli and short- to medium-range order in glasses. This chapter explores the behavior of glasses from the domain from elasticity to fracture. In this temperature range, they are usually seen as perfectly brittle materials: materials that deform only elastically, until they break. Remember these are for flat sections of solid glass, not shaped, lacquered, or laminated.This chapter focuses on the mechanical properties and behavior of glasses below their glass transition temperature. So your section of glass would weigh in at 25.5KGs.īelow is a handy list of glass thicknesses and their corresponding weights per M2.
So for instance: Say you had a section of 12mm thick glass, 1700mm x 500mm the equasion would be as follows. Glass Weight in KG = Area of glass M2 (Length x Width) x Thickness of the glass x 2.5KG. Should you be looking a more complex design and want our help working through the weight please do not hesitate to contact us. In the most simple form you just have to follow the equation below. Glass can be a surprisingly heavy material when used in large quantities so it is important to work out just how heavy your idea will be when fabricated in real life.Ĭalculating the weight of a section or sections of glass is relatively easy. Here at Glassdomain we take into consideration the weight of glass with all of our standard and bespoke designs.
