Author Description

This book provides information related to mechanical properties of advance ceramic, from preparing the sample for testing, and protocol for measurement the mechanical properties base on recent standard that available as well as improvement for established standard. Advance ceramics are hard and brittles so its mechanical properties addressed mainly to hardness testing and fracture toughness (KIC) testing. In chapter 1 of this book is introduced improvement of fracture toughness testing from the standard established that is using single edge V-notch beam (SEVNB) to become Single edge precrack v-notch beam (SEPVNB). The more valid result is obtained because real crack established at the tip of notch prepared for fracture toughness testing. New method in fabrication of advance ceramic is introduced in Chapter 2. The fabrication is introduced by Lithography Based Manufactured which is the product of advance ceramic is manufactured layer by layer such 3D printing. By this technique a complicated product can be obtained with having mechanical properties similar to one that produce by using conventional sintering method. The specific application of advance ceramicin renewable energy field is introduced in Chapter 3. The bearing of wind turbine for electric generation is manufactured by using advance ceramic of silicon nitride that is recognize as steel of ceramic. Wind turbine is constructed at elevated structure with difficulty in maintenance of the bearing. By using silicon nitride as a bearing, the wear of the bearing can be avoided for such a long time and maintenance cost can be reduced. The quality of silicon nitride as a bearing is tested by using hardness test method. In Chapter 4, the fracture toughness test by using established standard of American Society for Testing and Materials (ASTM) is introduced. The testing is conducted by provided micro crack by using knop indenter. The crack obtained in the shape of half circle and measurement of the rack size is measur
