DOI: 10.1016/j.ceramint.2019.09.068
Abstract: Abstract Fracture toughness, bending strength, Young's modulus, hardness and subcritical crack growth were determined for six different alumina/zirconia composites. The bending strength was modelled using Weibull distribution. The fracture toughness, bending strength and resistance to… read more here.

DOI: 10.1016/j.engfracmech.2019.03.010
Abstract: Abstract The initiation and growth of any crack require very high stresses, since the required stress, generally, is inversely proportional to the square root of its length, starting from elastic Griffith’s crack to elastic-plastic Orawan… read more here.
