Static and dynamic mechanical properties of Yttrium Aluminum Garnet (YAG)

Dynamic response of YAG polycrystalline and single‐crystal transparent ceramics: Experiments and mesoscopic simulations

“…According to the shock recovery experiments [9][10][11][12] , the mesoscopic damage of brittle ceramics usually involves fractures, fragments, and even void collapse. To simulate the mesoscale damage evolution information of the shocked polycrystalline ceramics, a few theoretical models were proposed in the past decades.…”

“…Although Jiang et al. reported on the HEL and spall strength of YAG polycrystalline ceramics under shock pressure below 17 GPa 9 , whether pressure‐dependent HEL exists in both YAG polycrystalline and single‐crystal transparent ceramics as well as the mechanism responsible for the HEL are not well known. To better understand the mechanical behaviors of YAG under loading, in this work, both planar impact experiments and mesoscopic simulations have been performed to study the dynamic response of YAG polycrystalline and single‐crystal transparent ceramic.…”

“…Transparent yttrium-aluminum-garnet (Y 3 Al 5 O 12 , YAG) has excellent mechanical properties (high Young's modulus and hardness) and low density, as well as lower manufacturing cost than other transparent ceramics, therefore, emerging as promising transparent armor. Although Jiang et al reported on the HEL and spall strength of YAG polycrystalline ceramics under shock pressure below 17 GPa 9 , whether pressure-dependent HEL exists in both YAG polycrystalline and single-crystal transparent ceramics as well as the mechanism responsible for the HEL are not well known.

Dielectric resonator antenna with Y3Al5O12 transparent dielectric ceramics for 5G millimeter‐wave applications

“…The higher the Q , the smaller the dielectric loss of the DRA, which can achieve better antenna radiation performance. Yttrium Aluminum Garnet (Y 3 Al 5 O 12 , YAG) transparent ceramics are potential candidates for 5G mm‐wave applications due to their excellent properties, such as suitable dielectric constant, low dielectric loss, corrosion resistance, high‐temperature stability, and high transparency 14–16 . Usually, two raw material powders Y 2 O 3 and Al 2 O 3 are mixed to prepare YAG transparent dielectric ceramics through solid‐state reaction sintering 17–20 .…”
