Are there any figures available for shear stress of annealed and toughened glass
Annealed glass is a type of glass that has undergone a process of slowly cooling down after being formed. The shear stress for annealed glass refers to the maximum force that can be applied to the glass before it breaks or fails.
Toughened glass, also known as tempered glass, is a type of glass that has undergone a process of rapid heating and cooling. This process makes the glass stronger and more resistant to breakage. The shear stress for toughened glass is typically higher than that of annealed glass, meaning it can withstand greater forces before breaking.
The shear stress of glass is affected by various factors, including the type of glass, its thickness, and the temperature. Annealed glass has a lower shear stress than toughened glass due to its slower cooling process, while the thickness and temperature of the glass can also impact its shear stress.
Shear stress is typically measured in units of Pascals (Pa) or Megapascals (MPa). The measurement can be obtained through various testing methods, such as the ASTM C1259 standard test method for dynamic shear modulus and damping of glass by Impulse Excitation of Vibration.
Understanding the shear stress of glass is crucial in various industries, such as construction and automotive, where glass is used in buildings and vehicles. Knowing the maximum force that glass can withstand helps in determining the appropriate type and thickness of glass to use in different applications for safety and durability purposes.
