Ceramic Elastic Deformation

Deformation can be elastic or plastic.

Ceramic elastic deformation.

Deformation can be elastic or plastic. Thermodynamically stable cavities can absorb vacancies 37. This force is known as strain. Understanding elastic deformation is very important in ceramics to eliminate instantaneous brittle fracture at some applied stress levels.

The complexity of the characters of ceramic materials enhances difficulties of evaluating the effect of various parameters on the plastic behavior of the materials. A temporary shape change that is self reversing after the force is removed so that the object returns to its original shape is called elastic deformation. Plastic deformation of ceramic materials. When an exterior stress is applied to a solid body the body tends to pull itself apart.

Understanding elastic deformation is very important in ceramics to eliminate instantaneous brittle fracture at some applied stress levels. Each atom tries to pull its neighbor as close as possible. 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. This causes a force trying to resist the deformation.
