Ceramic Elastic Deformation

This causes the distance between atoms in the lattice to increase.

Ceramic elastic deformation.

Deformation can be elastic or plastic. The fracture stress is usually the same or very close to the elastic limit. This change in shape is called deformation. This force is known as strain.

The complexity of the characters of ceramic materials enhances difficulties of evaluating the effect of various parameters on the plastic behavior of the materials. Grain and grain boundary processes contribute to plastic 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. Plastic deformation of ceramic materials.

Pores can reduce the load carrying cross section area cause local stress concentrations and lower elastic moduli. 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. 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.
