Originální abstrakt

The work deals with FE modelling of LTCC "Building blocks" (ceramic plate with inbuilt square silver electrodes) subjected to 4 point bending and with prediction of their cracking. The aim is to explain fracture behaviour observed in the experiment and predict critical forces leading to specimen failure. To determine the critical force necessary for the crack initiation (upon combined thermal and mechanical stresses) a stress-energy coupled criterion is employed. The work also studies influence of the electrode position within the ceramic height and discusses two possible points of the crack origination – surface of the specimen and tip of the electrode and explains which spot is more convenient for the inception of the cracking.
