      Elasto-Plastic Model.

AB  - This paper presents the methodology for predicting the mechanical performance of 
      structural elements made of polymer concrete (PC). A vinyl ester polymer concrete 
      composition and the results of experimental studies to determine the basic 
      mechanical properties of the material are presented. Following the strategy for 
      sustainable development in the building industry, the material cost of polymer 
      concrete was lowered by reducing the consumption of raw materials and the partial 
      replacing of the microfiller fraction with recycled waste products-calcium fly 
      ash. An accurate computational model enabling stress analysis is a convenient way 
      to verify the suitability of PC as a construction material in structural 
      applications. Due to difficulty in deriving an accurate analytical formula, 
      numerical approximation (finite element method) was used as a method for solving 
      the problem. Constitutive modeling of PC is a very important aspect of the 
      strength calculations and here it was done within the framework of 
      elasto-plasticity. Numerical evaluation of the static bearing capacity of PC 
      manhole covers is shown as an example of the proposed FEM methodology. The 
      results of computer simulations were compared with laboratory tests. Finally, the 
      adequacy of the numerical modeling for testing new construction and material 
      improvements is discussed. The study showed that the concrete damaged plasticity 
      material model can be effectively used for the description of PC mechanical 
      behavior.
