Crack Growth Resistance of Ceramic Composite

  • Seijiro Hayashi (a1), H. Baba (a1) and A. Suzuki (a1)


Fracture process zone in SiCw/Si3N4 ceramic composite was studied by a hybrid experimental-numerical analysis employing moire interferometry and finite element analysis. A chevron-notched, wedge-loaded double cantilever beam specimen was used to obtain a stable crack growth. The relation between crack closure stress and crack opening displacement which govern fracture process zone was obtained.
