Abstract
EN The paper addresses the problem of numerical modelling of sandwich panels exposed to fire temperatures. A complex spatial model is presented that takes into account the variation of material parameters with temperature. A cohesive interaction is defined between the panel layers, for which damage initiation and propagation criteria are provided. Thermal conductivity and radiation are also determined for this interaction and possible separation. In addition, support conditions simulating the experimental test conditions were defined. A combination of classical contact and point interactions using connectors is used for this purpose. The model is used to simulate fire exposure and compared with experimental results. The obtained results confirm that the model is suitable for predicting the general trend of panel behaviour during fire.
