【 摘 要 】

The article addresses the use of hyperelastic materials to evaluate the redistribution of stresses in a composite structural hollow brick by means of numerical analysis. Both rubber and concrete were modelled as hyperelastic materials with appropriate energy potential. The concrete was modelled on the Murnaghan potential, while the rubber was modelled on the Zahorski potential. The analysed prefabricated hollow brick was loaded with a force impulse. As a result, redistribution of effective stress was observed, which was important for the evaluation of the operation of the analysed prefabricated product. The presented numerical analysis was carried out using the ADINA program.
