Viscous deformation of glass refers to the process by which glass deforms slowly over time when under stress, similar to how a viscous fluid would deform. This deformation occurs at high temperatures, close to the glass's melting point, allowing the glass to flow and change shape. Over long periods, this phenomenon can cause glass objects to sag or slowly change their dimensions.

What is an example of high and low viscous material?
An example of a high viscous material is honey, which flows slowly due to its thickness. An example of a low viscous material is water, which flows easily because it has low resistance to deformation.
Is viscous a scalar or vector quantity?
Viscosity is a scalar quantity. It measures a fluid's resistance to deformation and is independent of direction in three-dimensional space.
What happens when glass melt?
When glass melts, the solid structure breaks down and the glass becomes a viscous liquid. The molecules rearrange and flow freely, allowing the glass to take the shape of its container. As it cools, the glass solidifies back into its rigid form.
What is meant by incompressible viscous fluid?
An incompressible viscous fluid is a fluid that does not change density when subjected to pressure and shear stress. In other words, its density remains constant under different pressures. Viscous fluid refers to the fluid's resistance to shear deformation or flow, indicating its thickness or stickiness.
What is visco elastic behavior?
Viscoelastic behavior is the combination of viscous (fluid-like) and elastic (solid-like) properties in a material. When subjected to stress, a viscoelastic material will exhibit both elastic deformation (instantaneous response) and viscous flow (time-dependent response). This behavior is commonly seen in polymers, biological tissues, and some fluids.
How deformation happens in non crystalline material?
In non-crystalline materials, deformation occurs through the movement of dislocations or structural defects. These materials lack the long-range order seen in crystalline materials, so deformation tends to happen through the rearrangement of atoms over a wider area, leading to plasticity. Non-crystalline materials deform through mechanisms such as viscous flow or ductile fracture, depending on their composition and structure.

What does viscosity mean for a liquid?
It is the ability of the liquid to flow. The higher the viscosity, the less the ability to flow. For example, oil is more viscous than water; honey is more viscous than oil.

Is it possible for a solid to be have like fluid?
No, although there are things which we think of as solids - such as glass - which are actually extremely viscous fluids.
