A research program on failure modes induced by spherical indenters in brittle layer structures bonded to polymeric substrates, in simulation of occlusal function in all‐ceramic dental crowns, is surveyed. Tests are made on model flat and curved layers bonded onto a dentin‐like polymer base, in bilay...
