Prediction of crack nucleation and propagation in porous ceramics using the phase-field approach

“…where g(d) is a degradation function introduced to take into account the material softening during damage. Among several options [57], g(d) is chosen, in this work, as a quadratic function with g(d) = (1 − d) 2 . It can be noticed that the numerical parameter α, which is assigned a very low positive value, is added to ensure the stability of the simulation when d tends to 1.…”

“…They benefit from the ceramic properties, which are known to be highly stable in corrosive and oxidizing environments. Moreover, they offer high thermochemical and mechanical stability, low thermal conductivity and small dielectric constant [1][2][3][4][5][6][7][8]. Thanks to all these features, porous ceramics are used as key components in several technological devices with far-reaching economic and ecological implications.…”

“…Thanks to all these features, porous ceramics are used as key components in several technological devices with far-reaching economic and ecological implications. They are currently employed in biology, medical industry, electronic engineering, petroleum industry, metallurgy, environment protection and chemical engineering [2][3][4][5][6]. In particular, porous ceramics have achieved an overwhelming success in the domain of energy.…”

Fracture properties of porous yttria-stabilized zirconia under micro-compression testing

“…In this frame, various studies have been already devoted to the fracture of porous ceramics. This class of functional materials can be used in many domains such as electronics, chemistry, biology and energy [1][2][3][4][5]. Porous ceramics are widely employed as they take advantage of the attractive properties of ceramic known to be stable in very aggressive environments [1][2][3][4][5][6][7][8].…”

Porous ceramics are widely employed as they take advantage of the attractive properties of ceramic known to be stable in very aggressive environments [1][2][3][4][5][6][7][8]. They also exhibit a good thermal shock resistance and a low thermal conductivity.…”
