25 Νοε 2010 · Young's Modulus (or Tensile Modulus alt. Modulus of Elasticity) and Ultimate Tensile Strength and Yield Strength for materials like steel, glass, wood and many more.
26 Νοε 2016 · Young’s modulus, E This modulus expresses the tensile force that would theoretically have to be applied to a glass sample to stretch it by an amount equal to its original length. It is expressed as a force per unit area.For glass, in accordance with European standards :
Chemical Aspects of Glass Strength ≡Si −O −Si ≡ + H2O ⇒ 2 [≡Si −OH] The presence of water or other polar substances greatly accelerates the crack propagation process • Ordinary bulk glass as a nominal strength of 70 MPa • Bulk synthetic glass [SiCl4 - derived] has a strength of 500 MPa [7X increase] due to fewer impurity defects

Float glass provides the material for all other forms of processed glass, such as laminated glass and toughened glass. This article outlines its production and some of its applications.
Mechanical and structural properties of sodium (NAFP) and zinc (ZAFP) iron±aluminum±phosphate bulk glass and ®bers have been investigated. Young's modulus of the ®bers was measured by a...
Elastic modulus is the stiffness of the glass, an important engineering property. Generally, the stiffness decreases with temperature. Colored glasses absorb radiation. The larger the photoelastic constant, C, the more birefringence is generated by a given stress. Conductivity in silicate glass is by charged ions.
