Effective Area And Effective Volume Calculations For Ceramic Test Specimens, Rahul Jain

ETD Archive

Calculation of effective volume and/or effective area is a key step in estimating reliability of ceramic component life cycle. Most common tests performed to assess the strength and reliability of components made from ceramics are bend bar specimens tested in three-point and four-point flexure, C-ring and O-ring specimen under diametral compressive or tensile loads and biaxial ring-on-ring specimens. ASTM closed form solutions for the effective volume and area exists for these specimen geometries which are based on classical theories with underlying assumptions. In general the closed form expressions are valid for limited specimen geometry bounds. An alternative numerical approach has …
