Method of Determining Elastic and Plastic Mechanical Properties of Ceramic Materials Using Spherical Indenters.

摘要

The invention pertains a method of determining elastic and plastic mechanical properties of ceramics, intermetallics, and other hard, brittle materials which fracture prior to plastically deforming when tensile loads are applied. The invention provides an improved means to characterize the plastic and elastic deformation of these materials. It is particularly suitable as a materials characterization method and quality control method for manufacturers and users of these materials. The method measures the plastic and elastic deformation of hard, brittle materials with low ratios of elastic modulus to hardness.
