Abstract

In presented paper the composite wall structure made of concrete and Zahorski/Mooney Rivlin rubber cross pads subjected to impact loads was investigated. Mentioned rubber cross pads were assumed to be inserted or injected in specially formed holes during the production process. Moreover, two different impact loads were taken into further considerations - pressure and concentrated force. Such impact loads due to the small time step size allowed observation of mechanical wave propagation in analyzed structure in the form of stress plots. On the basis of composite wall comparison with the solid concrete wall it could be stated that the mechanical wave propagation was significantly damped via inserted/injected rubber cross pads. Discussed problem was solved with the use of finite element method using ADINA program.
