Ceramic Elastic Deformation

Understanding elastic deformation is very important in ceramics to eliminate instantaneous brittle fracture at some applied stress levels.

Ceramic elastic deformation.

The fracture stress is usually the same or very close to the elastic limit. Deformation can be elastic or plastic. Thermodynamically stable cavities can absorb vacancies 37. When an exterior stress is applied to a solid body the body tends to pull itself apart.

Deformation can be elastic or plastic. The complexity of the characters of ceramic materials enhances difficulties of evaluating the effect of various parameters on the plastic behavior of the materials. Each atom tries to pull its neighbor as close as possible. Understanding elastic deformation is very important in ceramics to eliminate instantaneous brittle fracture at some applied stress levels.

This causes a force trying to resist the deformation. This force is known as strain. There axe very few ceramic materials free of pores that are also free of a glassy phase which 81 was present as a liquid during firing. When a sufficient load is applied to a metal or other structural material it will cause the material to change shape.
